What are the predisposing factors for dental caries?

The emergence of dental caries, so that people are very painful intolerable, serious harm to patients, but also the psychological impact on patients. What are the predisposing factors for dental caries? This is what people have to understand. Only to understand the predisposing factors, in order to carry out effective prevention in daily life. Xiaobian below for everyone to explain in detail about the causes of dental caries which.
1. bacteria
Is a necessary condition for the occurrence of caries, it is generally believed that there are two types of cariogenic bacteria, one is the production of bacteria, mainly Streptococcus mutans, actinomycetes and Lactobacillus, Carbohydrate decomposition can produce acid, resulting in Tooth non-organic demineralization; the other is a Gram-positive cocci, can damage organic matter, after a long period of time can make teeth formation cavities. Currently recognized as the main cariogenic bacteria Streptococcus mutans, the other also includes actinomycetes, Lactobacillus and so on.

Bacteria are mainly attached to the tooth surface with plaque. Stopped food in the carbohydrate degradation, on the one hand polymerization to produce high viscosity dextran, the formation of plaque matrix, on the other hand acid to demineralize the teeth, plaque composition is more complex, in addition to a large number of bacteria, Sugar, protein, enzymes and other substances.
2. Oral environment
Oral cavity is the outer environment of the teeth, and the occurrence of caries is closely related to, which play a leading role in food and saliva.
(1) food is mainly carbohydrates, both with the formation of plaque matrix, but also plaque bacteria in the main energy, bacteria can use carbohydrates (especially sucrose) metabolism of acid, and synthesis of extracellular polysaccharides and intracellular polysaccharide , The organic acid produced is conducive to the growth of acid and acid bacteria, but also conducive to the hardening of the hard tissue of the teeth, polysaccharides can promote the adhesion and accumulation of bacteria in the tooth surface, and in the absence of exogenous sugar, to provide energy source. Therefore, carbohydrates are the basis of the caries disease.
(2) saliva in the normal circumstances, saliva has the following effects:
Mechanical cleaning to reduce the accumulation of bacteria.
Antibacterial effect of direct antibacterial or inhibition of plaque attached to the tooth surface.
Antacid effect by the heavy bicarbonate and other substances from the role of neutralization.
Anti-dissolving effect through the calcium, phosphorus, fluoride and other teeth to enhance acid resistance, reduce the solubility.
The amount and quality of saliva fluid changes, can affect the caries rate, clinically visible, dry mouth or saliva secretion in patients with caries rate increased significantly. The maxillofacial radiotherapy may be due to the destruction of the salivary glands and the presence of multiple caries; on the other hand, when the amount of lactic acid in the saliva is increased or the bicarbonate content is reduced, it is also beneficial to the occurrence of caries.
3. host
The tooth is the target organ in the process of caries. The shape of the tooth, the degree of mineralization and the structure of the tooth are directly related to the occurrence of caries, such as the fissure of the teeth and the teeth with poor mineralization, and the degree of mineralization The structure of the teeth and the body is closely related, especially in the development, not only affect the development and structure of the teeth, but also on the saliva flow, the amount of fluoride, Flow rate and its composition also has a great impact, and therefore is an important part of the occurrence of caries.
Time
Caries disease has a long process, from the initial caries to the clinical formation of cavities generally need 1.5 to 2 years, so even if the cariogenic bacteria, the appropriate environment and susceptible host coexistence, dental caries will not occur immediately, Only the above three factors exist for a long time, it may produce caries, so the time factor in the occurrence of dental caries is of great significance.
The above is a small series for the details of the caries of the induced factors, we hope to have some help. At the same time experts advise you: for the health of the teeth, we must maintain oral hygiene, develop good habits, active and effective prevention of dental caries.

What are the causes of dental caries?

Now a lot of people have the phenomenon of dental caries, dental caries is a very common disease, the disease to patients with a great deal of pain. A serious impact on the lives of patients, we all know that there are many reasons in life can cause dental caries, but the specific reasons? Xiaobian for the following detailed description of what, the cause of dental caries what.
Caries is a multi-factor disease, mainly including three aspects: bacteria, diet, teeth and saliva, the three are interrelated, the lack of one can not occur caries. Current scholars believe that saliva as the external environment of the teeth, is an important factor affecting dental caries.

1. bacteria
Caries occurrence and development process, because the bacteria in the incidence of dental caries play a leading role, therefore, in recent years internationally recognized caries is a bacterial disease caused by caries a lot of bacteria, the most important is some Streptococcus mutans and Lactobacillus The These bacteria are mixed with mucin and food debris in saliva and are firmly adhered to the tooth surface and the fissure. This adhesive is called dental plaque or dental plaque. Plaque in a large number of bacteria produce acid, resulting in plaque below the enamel surface decalcification, dissolved. Clinical studies have shown that dental plaque and more dental caries are also more.
2. diet
In the process of dental caries, diet is an important indicator of bacteria. Food contains a lot of carbohydrates and sugar, these substances not only supply plaque bacteria life and activity of energy, but also through the role of bacterial metabolism to produce glycolic acid, acid long-term retention in the tooth surface and fissure, the enamel off Mine damage, followed by some of the bacteria and the protein dissolved to form cavities. Caries a lot of carbohydrates, the most important is sucrose.
Dental development period, nutrition determines the biochemical structure of dental tissue, good calcification of the teeth with high caries resistance. If the food contains mineral salts, the main vitamins and trace elements such as calcium, phosphorus, vitamin B1, D and fluoride and other deficiencies, dental caries resistance is low, causing the incidence of dental caries. Deciduous teeth in the fetus that has occurred, development and calcification, the mother of the new breast nutrition, although the development of fetal deciduous teeth, although there is no decisive impact, but the strengthening of maternal nutrition is still beneficial to the calcification of deciduous teeth. Unless the mother suffering from severe metabolic or genetic disease, the general deciduous teeth is not easily affected.
3. teeth
The shape, structure and location of the teeth are significantly related to the incidence of dental caries. Dental teeth and fissure is the development of the process of leaving defects, deep fissure is easy to stay cells and food debris, and difficult to remove, easy to induce dental caries. Mineralization, especially calcified teeth, enamel and dentin density is not high, low caries resistance, susceptible to dental caries. Fluoride in the mineral mineralization structure is very small, but it is important to enhance the caries resistance of the teeth. Teeth containing the amount of fluoride is not easy to occur dental caries. Deciduous teeth and young permanent teeth of the structure and degree of calcification are not mature enough, so susceptible to caries factors, the prevalence of caries rate.
Saliva is the outer environment of the teeth, plays a buffer, washing, anti-rust or antibacterial effect. Large and thin saliva can wash the surface of the teeth, reducing the accumulation of bacteria and food debris. The amount of small and thick saliva easy to stay, to help plaque formation and adhesion on the tooth surface. The nature and composition of saliva affect its buffering capacity and also affect the living conditions of bacteria.
This article for everyone to introduce some of the causes of dental caries, dental caries caused by a variety of reasons, mostly with everyone's diet, Xiao Bian here prompted readers friends, dental caries is very big, so the parents for the future of the child To do a good job for the prevention of dental work.

Why do children die more susceptible to dental caries

Many parents found that the baby's deciduous teeth began to long teeth, and found that most of the children around also have dental caries. Parents will doubt why children are more likely to suffer from dental caries teeth? Here we look at the reasons, we hope to help.
There are two reasons for this.

On the one hand, children oral unclean, infants and young children will not gargle, will not brush your teeth, although the elderly will be mouthwash, will brush your teeth, but most children mouthwash, brush your teeth is not serious, can not adhere to early and late brushing, after eating Mouthwash, so stay in the teeth between the gap and the food residue.
On the other hand, children like to eat snacks, especially like to eat sugar, and even some children's mouth with sugar to sleep. We know that there are many bacteria in the mouth, especially lactobacilli, can make sugar and food residue fermentation, resulting in a lot of lactic acid, this acid can damage the tooth structure, the occurrence of dental caries. On the other hand, pediatric nutritional status is not good, such as children suffering from malnutrition, rickets and a variety of chronic diseases, especially those suffering from vitamin D deficiency rickets in children, due to lack of calcium teeth, tooth structure loose, more likely to be lactate erosion formation of dental caries The
Above to give you the reasons for children suffering from deciduous teeth more likely to suffer from dental caries, parents should be more important for the prevention of child dental caries, children suffering from dental caries are mostly affected and bad habits caused by, if the child was found to have dental caries, Be sure to take him to treatment in time.

What are the causes of dental caries?

Now more and more young children are suffering from dental caries, a large part of the reason is that parents usually do not do well in nursing work, and pediatric caries to children to bring the damage is still more, but also lead to a lot of concurrent Disease, the child's health is detrimental, so sick to timely treatment, then lead to the cause of child dental caries is what?

⑴ children eat sugar and other sweets too much;
⑵ lack of calcium
⑶ do not pay attention to oral hygiene.
The above three points is the main reason for children with dental caries, parents should care about children, education children from childhood to develop good habits, eat sweets, pay attention to oral hygiene, develop good morning and evening brushing habits, parents should also pay attention to children Add calcium, prevent tooth decay.
2, the symptoms of dental caries how?
If the parents find that the child's teeth are not suited to the timely access to the hospital dental treatment, life, many people do not feel fuss, probably because the child is in the dressing stage should be no big problems, but perhaps your temporary negligence may lead to bad Of the consequences, then the symptoms of infant caries is what?
Child dental caries is the teeth are often affected by oral acid attack, so that enamel corrosion, soft discoloration, and gradually developed into a substantial defect and the formation of cavities. Cavities will not self-healing, if not remediation will continue to corrode to dentin, pulp, leaving only the roots.
Caries not only make children feel tooth pain and affect appetite, chewing, digestion, absorption and growth and development, sometimes lead to pulpitis, alveolar abscess, and even cause systemic diseases, affecting children's health.
Parents can understand the main symptoms of dental caries in the above, so that parents have a more scientific understanding of the health of children with caries, if you find the above symptoms, please go to the hospital, early diagnosis and early treatment, to avoid tooth decay more serious.

What is the cause of dental caries?

Experts say: dental caries is that we often talk about tooth decay, or insect teeth, are generally caused by infection, such as infection of bacteria, etc., of course, the incidence of oral health and also have a direct relationship between people who eat sugar The odds of dental caries are very large, mainly because of the sticking of sugar on the tooth surface.

       1, bacteria
       Bacteria is a necessary condition for the occurrence of caries, it is generally believed that there are two types of caries, one is the acid bacteria, mainly Streptococcus mutans, actinomycetes and Lactobacillus, carbohydrate decomposition can produce acid, Leading to tooth mineralization of inorganic matter; the other is the Gram-positive cocci, can damage the organic matter, after a long period of time can cause dental cavities. Currently recognized the main cariogenic bacteria is Streptococcus mutans, the other also includes actinomycetes, Lactobacillus and so on.
       Bacteria are mainly attached to the tooth surface with plaque. Stopped food in the carbohydrate degradation, on the one hand polymerization to produce highly viscous dextran, the formation of plaque matrix, on the other hand acid bleaching teeth, plaque composition is more complex, in addition to a large number of bacteria, Sugar, protein, enzymes and other substances.
       2, oral environment
       Oral cavity is the outer environment of the teeth, and the occurrence of caries is closely related to, which play a leading role in food and saliva.
       (1) food is mainly carbohydrates, both with the formation of plaque matrix, but also plaque bacteria in the main energy, bacteria can use carbohydrates (especially sucrose) metabolism of acid, and synthesis of extracellular polysaccharides and intracellular polysaccharide , The organic acid produced is conducive to the growth of acid and acid bacteria, but also conducive to the hardening of the hard tissue of the teeth, polysaccharides can promote the adhesion and accumulation of bacteria in the tooth surface, and in the absence of exogenous sugar, to provide energy source. Therefore, carbohydrates are the basis of the caries disease.
       (2) saliva in the normal circumstances, the saliva has the following effects:
       Mechanical cleaning to reduce the accumulation of bacteria.
       Antibacterial effect of direct inhibition or inhibition of plaque attached to the tooth surface.
       Antacid effect by the heavy bicarbonate and other substances from the role of neutralization.
       Anti-dissolving effect through the calcium, phosphorus, fluoride and other teeth to enhance acid resistance, reduce the solubility.
       3, the host
       The tooth is the target organ in the process of caries. The shape of the tooth, the degree of mineralization and the structure of the tooth are directly related to the occurrence of caries, such as the fissure of the tooth and the teeth with poor mineralization, and the degree of mineralization The structure of the teeth and the body are closely related, especially in the development, not only affect the development and structure of the teeth, but also on the saliva flow, the amount of fluoride, Flow rate and its composition also has a great impact, and therefore an important part of the occurrence of caries.
       4, time
       Caries disease has a long process, from the initial caries to the clinical formation of cavities generally need 1.5 to 2 years, so even if the cariogenic bacteria, the appropriate environment and susceptible host coexistence, dental caries will not occur immediately, Only the above three factors exist for a long time, it may produce caries, so the time factor in the occurrence of dental caries is of great significance.
       Saliva is also a major factor leading to dental caries, under normal circumstances, saliva cleaning bacteria, antibacterial effect, it can be said that saliva under normal circumstances, will play a role in the protection of teeth. But when the amount of saliva, and the quality of change, there is the risk of dental caries or other dental diseases.

What is the risk of dental caries in children

In recent years, the incidence of dental caries in children is getting higher and higher, the disease to the child's physical and mental health to bring a great impact, parents and friends you are still indifferent? Prevention of dental caries is very important, parents must early prevention. Here, to the parents and friends to introduce the cause of childhood caries seven reasons.

(1) teeth just eruption, the degree of calcification of the teeth is low, the surface is not smooth and there are many micropores, such teeth are poor acid resistance, bacteria easy to cat attached to the tooth surface formation plaque, it is prone to dental caries.
(2) the beginning of the teeth, especially the young permanent teeth bite the surface of the ditch, nest, the gap and more deep, where easy to stay in food stuck, hidden bacteria, and brush your teeth, mouthwash is not easy to clean, so easy to suffer from caries The
(3) children teeth chewing function is weak, eat mostly soft food, and which often contains a lot of sugar, easy to produce acid, and prone to dental caries.
(4) eating snacks The current children's food is mostly high sugar content, strong consistency, J soft and fine food, such as cakes, bread, biscuits, all kinds of candy, milk and a variety of beverages are Children like food. These foods due to long-term kill attached to the spear on the easy fermentation of acid, erosion of teeth and dental caries.
(5) poor oral hygiene. Infants can not brush their own teeth, most children brush their teeth, not serious, the method is not correct. Children are young and ignorant, almost all have bad snacks and not clean the bad habits of teeth. When asked about tooth care children brush a few teeth a few times a day, how long each time the brush, the parents replied, "brush your teeth is to go through the motions, each brush more than thirty seconds, short a few seconds." This sloppy treatment Bad habits of teeth, of course, susceptible to caries.
(6) children sleep a long time, sleep when the mouth is at rest, saliva secretion decreased, low flow rate, saliva mechanical flushing effect decreased. Due to reduced saliva secretion, saliva in some of the antimicrobial substances, lysozyme and other beneficial to the health of the teeth and the amount of reduction, which is conducive to the breeding of bacteria, some bad habits of children, such as eating bread before going to bed, pastries, etc. do not brush your teeth To sleep bad habits, some children have included? Sugar sleep bad habits, so more likely to induce caries.
(7) Parents often think that deciduous teeth are temporary, rotten not much impact, and thus lack of attention to children's caries, failed to timely treatment, which will inevitably increase the development of caries factors.
More than seven children cause dental caries can be eliminated, and now we all know the cause of children's dental caries it, Xiaobian hope that children parents must correct some of the child's bad habits, pay attention to the child's mouth clean, and take some necessary Anti-caries measures.

What is the cause of dental caries formation?

Dental caries is no stranger to us, because most of us will have a few caries, it is in a serious time to affect our diet, so we can not neglect the disease. Most of us think that dental caries are caused by too much sugar, which is only caused by this factor? To see how the experts introduced the formation of dental caries it!
The medical profession after a long study that: dental caries is roughly by the four pathogenic factors together results.
They are bacteria, food, teeth and time the mouth of a large number of bacteria to survive, some of which bacteria such as Streptococcus mutans, actinomycetes, lactobacilli have the ability to produce harmful teeth of the chemical substances, although the teeth hard, chewing food Wear on it is very small, but these chemicals can be a short time to gradually break down the destruction.

Bacteria in the tooth surface to form a thin film, medically known as plaque, bacteria is to plaque as a base to attack the teeth. Bacteria produce harmful chemicals that require raw materials, and these raw materials are supplied by the carbohydrate substances in the food.
Food on the one hand to supply the body to nutrition, so that the teeth more solid and enhance the anti-caries ability of the teeth; the other hand, the food contains carbohydrates after chewing swallow, part of the residual in the mouth, the use of cariogenic bacteria, Teeth with corrosive substances, thereby breaking the teeth hard tissue, which led to the occurrence of dental caries.
Due to genetic, nutritional and other factors led to the development of different levels of calcification, the degree of calcification of the teeth, the teeth surface uneven, enamel layer is relatively weak, easy to be destroyed; In addition, the teeth are arranged irregular, easy residue of food residues, But also susceptible to dental caries.
Time-induced caries The use of nutrients in food residues to produce destructive substances takes some time.

How does dental work occur?

As we all know, the problem of teeth, in fact, is not visible to the naked eye insects, in fact, it is not caused by a cause but by other causes caused by a lot of other people want to know is the caries How to treat? How to treat dental caries is the best treatment.
How does dental work occur?
The first is food. Edible rough food has a certain self-cleaning anti-caries effect, eating rough food is not easy to produce more abundant plaque and accumulation of more acid, which is difficult to form the condition of caries disease. And refined foods in the sugar content of more rough food, sugar into the plaque, plaque within the caries bacteria to sugar fermentation, the formation of a variety of acids, these acids stay in the tooth surface longer, the hard tissue of the teeth dissolved And produce caries. During the development of the teeth, it is more harmful to eat sugar between meals and before going to sleep.
Second, the presence of bacteria is a major condition for the occurrence of dental caries. Dental plaque is an important environment for bacteria to produce caries on the tooth surface. Oral hygiene is also a condition of dental caries, good oral hygiene to control plaque formation, thus controlling the occurrence of dental caries.

The third is the host. Host refers to the degree of susceptibility to caries, the host of the sensitivity of the caries involved in a variety of factors, such as saliva flow rate, flow, composition, tooth morphology and structure, the body's general condition. Teeth arranged irregular, crowded, overlapping at the risk of caries. Saliva has the role of cleaning teeth, saliva of certain ingredients on dental caries and periodontal disease can play a role in inhibiting. Others such as genetic, nutritional, mineral, endocrine on the host of caries have a certain impact.
The fourth is time. The occurrence and development of caries is a rather slow process, the time it takes for the carbohydrate to remain on the tooth surface, the time required for the tooth to erupt, and the time from plaque formation to caries, An important factor in the disease.
Tips: We now have a certain understanding of dental caries, but also know what is the cause of dental caries, suffering from dental caries patients to check and treatment as soon as possible, so as not to give your life with the inconvenience of the trouble!

Why the elderly will suffer from dental caries

We all know that old teeth are not good, like our grandparents often do not eat some of the more hard food or more sour things, there are many old teeth are gone, by wearing dentures to eat, mostly due to the elderly Dental caries cause teeth can not be normal chewing food, is not the proportion of elderly patients with high incidence of dental caries Why old age suffering from dental caries?
1. Saliva secretion reasons:
Elderly due to salivary gland function decline. Alveolar bone and gingival recession, increased interdental space, food impaction increased, the normal physiological environment within the mouth gradually destroyed. Oral self-purification effect decreased. Salivary gland secretion of lysozyme content is also low, oral bactericidal ability decreased, so that caries can be a large number of elderly dental caries breeding opportunities, leading to increased prevalence of dental caries in the elderly.
2. Dietary reasons:
Old age, due to various causes of chewing function decline, digestive function decline, forcing the elderly in the diet with a lot of refined flour and sugar, and reduce the intake of fibrous food: research confirmed that sucrose can accelerate oral Streptococcus mutans Of the reproduction, while the role of other sugar is very small. High-sugar diet has obvious caries: refined sugar in the oral bacteria involved in the fermentation products, under the appropriate conditions (temperature, humidity, stay in a certain location), for the hard tissue of the teeth gradually play decalcified dissolved The role, causing dental caries.

3. Cause of the tooth itself:
Old body hard tissue itself, the ability of metabolic decline, the hard tissue becomes fragile and easy to break, acid and anti-caries ability weakened, it is often the majority of teeth suffering from caries, the development of faster. Bad teeth formed by the crown caries cavity, in addition to containing a large number of cariogenic bacteria, there are still other types of pathogens, often cause senile pharyngitis, upper respiratory tract infection, and even pneumonia.
4. Body reasons:
Human growth and development period, if to ensure a rich and reasonable nutrition, it will form a healthy tooth jaw and normal teeth jaw anatomical morphology, into the old age and old age anti-caries ability will remain at a certain level, Occurrence of caries. And suffering from chronic wasting disease in the elderly, reduce the immune function of the body, so that the incidence of dental caries greatly increased, such as tuberculosis, diabetes.
The above is the cause of old age suffering from dental caries, with age, the immune system will gradually decline, so the chance of illness will increase to remind the elderly must develop good eating habits and oral hygiene habits, eat Light food, have good teeth, in order to have a better life.

What is the relationship between dental caries formation and fluoride?

Dental caries is one of the multiple dental diseases, suffering from dental caries will have a serious impact on the impact of patients. We usually listen to oral doctors recommend brushing with fluoride toothpaste, the teeth are good. Why is this? What is the relationship between the formation of dental caries and fluoride in the end? Here, we come together to listen to the experts to explain.
The main component of teeth and bones is hydroxyapatite, fluoride ions and carboxylate apricot have a greater affinity, and can be hydroxyapatite in the carboxyl replaced. Nitrogen-containing apatite is more solid and is not easily soluble in acids.
However, the bacteria in the mouth can make the residual sugar in the mouth of the sugar into the acid, leaving the hydroxyapatite slowly dissolved, resulting in tooth enamel off, causing insect teeth or dental caries, that is, dental caries.
Fluorine enamel has the ability to resist corrosion of acid, not only to avoid suffering from dental caries disease, and not because of the slow dissolution caused by senile osteoporosis, so the medicine is often used to repair stove with nitrous oxide teeth The
Normal adult dental fluoride content for each hundred grams of teeth in fluoride 11 mg, the amount of fluoride in the bones also increased with age. People's blood and tissues also contain tiny amounts of fluoride. Can promote wound healing, intestinal absorption of iron, to help nerve conduction and some of the enzyme metabolism.

In the daily life should strengthen the intake of fluoride. Human fluoride comes from drinking water and food, mainly drinking water. Fluorine in food more seafood, tea, fluoride is also concentrated in the epidermis of food, so eat skin food and coarse rice to avoid lack of fluoride. Experts advise, because the impact of fluoride on our teeth is great. We usually pay more attention to the intake of fluoride, so that we will stay away from dental caries, there is a more healthy teeth.
      Above for the readers to introduce the formation of dental caries and fluoride in the end what is the relationship between suffering from dental caries will indeed affect the lives of patients. Suffering from dental caries are generally more diet, with people's habits are also related to fluoride on the teeth is good, so we should eat some fluoride food to keep the teeth healthy.

What is the cause of dental caries?

Many patients are suffering from caries, dental caries is very common, although the caries will not give patients much harm, but in the onset of dental caries or pain, but why people suffering from dental caries? In addition to oral bacteria and other reasons What other reasons to induce dental caries? Here on this issue to explore the causes of dental caries are what.
1, bacteria: bacteria is a necessary condition for the occurrence of caries, is generally believed that there are two types of caries, one is the acid bacteria, mainly Streptococcus mutans, actinomycetes and Lactobacillus, can carbohydrates Decomposition of acid, resulting in tooth mineralization. Bacteria are mainly attached to the tooth surface with plaque.
2, oral environment: (1) food is mainly carbohydrates, both with the formation of plaque matrix, but also plaque bacteria in the main energy, bacteria can use carbohydrates (especially sucrose) metabolism of acid, and synthetic extracellular Polysaccharides and intracellular polysaccharides, produced by the organic acid is conducive to acid and acid bacteria growth, but also conducive to the hard tissue of the demineralization.

(2) saliva in the normal circumstances, the saliva has the following effects: mechanical cleaning to reduce the accumulation of bacteria. Antibacterial effect of direct inhibition or inhibition of plaque attached to the tooth surface. Antacid effect by the heavy bicarbonate and other substances from the role of neutralization. Anti-dissolving effect through the calcium, phosphorus, fluoride and other teeth to enhance acid resistance, reduce the solubility.
3, the host: the tooth is the target organ in the process of caries, the shape of the teeth, mineralization and organizational structure and caries have a direct relationship, such as the teeth of the pit and poor mineralization of the teeth more susceptible to caries, and Mineralization is better, the organization of fluorine content of the appropriate tooth caries strong; the other hand, the structure of the teeth and the body are closely related.
Through the above description can be seen to induce dental caries is also a lot of reasons, dental caries once the pain is still very uncomfortable, so we should be in the daily should keep oral hygiene and clean, regular oral care, so as not to cause some oral diseases.

What causes the occurrence of dental caries

Most of the caries are still in the baby's body, there are many parents that sooner or later the teeth will be permanent teeth to replace, so many parents think that suffering from dental caries is irrelevant. Caries on the baby's physical and mental health has a serious harm, and even suffer from life.
Caries is a bacterial disease, so it can be secondary to pulpitis and periapical periodontitis, and even can cause alveolar bone and jaw inflammation. Secondary infection of dental caries can form lesions, resulting in or add arthritis, periostitis, chronic kidney and other systemic diseases.
The currently recognized theory of caries etiology is a quadruple factor theory, mainly including bacteria, oral environment, host and time, the basic points are: caries-eating foods (especially sucrose and refined carbohydrates) in sugar, tightly attached to The surface of the tooth surface formed by the saliva protein is not only firmly attached to the tooth surface in this anatomical structure and biochemical and biophysical characteristics of the tooth surface, but also at a suitable temperature for a sufficient time Plaque deep acid, erosion of teeth, so that demineralization, and thus damage the organic matter, resulting in cavities.
1. bacteria
Is a necessary condition for the occurrence of dental caries, generally believed that there are two types of cariogenic bacteria, one is the production of bacteria, mainly Streptococcus mutans, actinomycetes and Lactobacillus, carbohydrates can cause acid decomposition, resulting in Tooth non-mineral demineralization; the other is the Gram-positive cocci, can damage organic matter, after a long period of time can make teeth forming cavities. Currently recognized the main cariogenic bacteria is Streptococcus mutans, the other also includes actinomycetes, Lactobacillus and so on.
Bacteria are mainly attached to the tooth surface with plaque. Stopped food in the carbohydrate degradation, on the one hand polymerization to produce highly viscous dextran, the formation of plaque matrix, on the other hand acid bleaching teeth, plaque composition is more complex, in addition to a large number of bacteria, Sugar, protein, enzymes and other substances.
2. Oral environment
Oral cavity is the outer environment of the teeth, and the occurrence of caries is closely related to, which play a leading role in food and saliva.
(1) food is mainly carbohydrates, both with the formation of plaque matrix, but also plaque bacteria in the main energy, bacteria can use carbohydrates (especially sucrose) metabolism of acid, and synthesis of extracellular polysaccharides and intracellular polysaccharide , The organic acid produced is conducive to the growth of acid and acid bacteria, but also conducive to the hardening of the hard tissue of the teeth, polysaccharides can promote the adhesion and accumulation of bacteria in the tooth surface, and in the absence of exogenous sugar, to provide energy source. Therefore, carbohydrates are the basis of the caries disease.
(2) saliva in the normal circumstances, the saliva has the following effects:
Mechanical cleaning to reduce the accumulation of bacteria.
Antibacterial effect of direct inhibition or inhibition of plaque attached to the tooth surface.
Antacid effect by the heavy bicarbonate and other substances from the role of neutralization.
Anti-dissolving effect through the calcium, phosphorus, fluoride and other teeth to enhance acid resistance, reduce the solubility.
The amount and quality of saliva fluid changes, can affect the caries rate, clinically visible, dry mouth or saliva secretion in patients with caries rate increased significantly. The maxillofacial radiotherapy may be due to the destruction of the salivary glands and the presence of multiple dental caries. On the other hand, when the amount of lactic acid in the saliva is increased or the bicarbonate content is reduced, it is also beneficial to the occurrence of caries.

3. host
The tooth is the target organ in the process of caries. The shape of the tooth, the degree of mineralization and the structure of the tooth are directly related to the occurrence of caries, such as the fissure of the tooth and the teeth with poor mineralization, and the degree of mineralization The structure of the teeth and the body are closely related, especially in the development, not only affect the development and structure of the teeth, but also on the saliva flow, the amount of fluoride, Flow rate and its composition also has a great impact, and therefore an important part of the occurrence of caries.
Time
Caries disease has a long process, from the initial caries to the clinical formation of cavities generally need 1.5 to 2 years, so even if the cariogenic bacteria, the appropriate environment and susceptible host coexistence, dental caries will not occur immediately, Only the above three factors exist for a long time, it may produce caries, so the time factor in the occurrence of dental caries is of great significance.
More than Xiaobian has been introduced for the reasons leading to the occurrence of dental caries, Xiao Wen warm tips if you find the baby suffering from the disease must be taken seriously, to go to a regular professional hospital diagnosis and positive treatment.

What are the predisposing factors of dental caries?

The emergence of dental caries, so that people are very painful, intolerable, serious harm to patients, but also on the patient's psychological impact. Then what are the predisposing factors of dental caries? This is what people have been trying to understand. Only by understanding the causative factors can we effectively prevent it in our daily life. The following Xiaobian for everyone to introduce what factors are caused by caries.
1. bacteria
Is a necessary condition for dental caries, generally there are two types of cariogenic bacteria, is a genus of acid producing bacteria, including Streptococcus mutans, Actinomyces and Lactobacillus, can make the decomposition of carbohydrates to produce acid, inorganic lead to tooth demineralization; the other is a gram positive cocci, can destroy the organic after the matter, long-term effect can make the tooth formation of cavity. At present, the main cariogenic bacteria are Streptococcus mutans, others include actinomyces, Lactobacillus and so on.
Bacteria adhere mainly to the surface of the tooth with plaque. Oral retention of carbohydrates were degraded after a polymerization to produce high viscous dextran, forming plaque matrix, on the other hand, the acid production of tooth demineralization, plaque composition is more complex, in addition to a large number of bacteria, and sugar, protein, enzyme and other substances.
2. oral environment
The oral cavity is the external environment of the teeth, which is closely related to the occurrence of caries, and the main functions are the food and saliva.
(1) the food is mainly carbohydrates, is associated with the formation of plaque matrix, is also the main energy bacteria in plaque, bacteria can use carbohydrates (sucrose) and acid metabolism, synthesis of extracellular polysaccharide and intracellular polysaccharide, organic acids produced in favor of acid production and acid bacteria the growth, also conducive to demineralization of dental hard tissue, the polysaccharide of bacteria in adhesion and promote the accumulation of the tooth surface, and the exogenous sugar deficiency, provide a source of energy. Carbohydrates are therefore the material basis for dental caries.
(2) the salivary fluid is under normal circumstances, the saliva has the following several functions:
The act of mechanical cleaning reduces bacterial accumulation.
Bacteriostasis, direct inhibition or inhibition of plaque on the surface of teeth.
The acid action is neutralized by substances such as bicarbonate.
The anti - acid action can increase the acid resistance and reduce the solubility of the teeth through calcium, phosphorus and fluorine.
When the quantity and quality of saliva changes, the rate of caries can be affected. In clinical practice, the incidence of caries in patients with xerostomia or saliva secretion increases obviously. Patients with maxillofacial radiotherapy may have multiple dental caries due to destruction of the salivary glands. On the other hand, when the amount of lactic acid in the saliva is increased or the amount of bicarbonate is reduced, it is also beneficial to caries.
3. host
The tooth is a target organ in the process of dental caries, there is a direct relationship between the degree of mineralization and the morphology, structure and caries, such as dental fissure and mineralized teeth caries bad easily, and the degree of mineralization is better, the appropriate amount of tissue containing fluoride dental caries resistance is strong; on the other hand, there is a close relationship between the structure and the body of the teeth, especially in the development, development and structure not only affects the teeth, but also has great influence on the flow and the flow rate of saliva and its composition, which is also an important part in the occurrence of dental caries.

4. time
The incidence of dental caries is a long process, the formation of cavity usually takes 1.5-2 years from early caries to clinical, so even if the cariogenic bacteria, suitable environment and susceptible to caries exist at the same time, also will not happen immediately, only these three factors also exist for a long time, can cause caries, so the time factor has important significance in the occurrence of dental caries.
The above is Xiaobian for everyone in detail the cause of caries, and we hope to have some help. At the same time, experts remind you: for the health of the teeth, we must maintain oral hygiene, and develop good habits and habits, and actively and effectively prevent dental caries.

What are the causes of dental caries?

A lot of people are suffering from dental caries. Dental caries is a very common disease, which brings great pain to the patients. Seriously affect the lives of patients, we all know that in life there are many reasons that can cause dental caries, but what are the specific reasons? The following Xiaobian for you to introduce in detail, what are the causes of dental caries?.
Dental caries is a multifactorial disease, mainly including three aspects: bacteria, diet, teeth and saliva, the three are related to each other, and lack of one aspect of dental caries can not occur. At present, scholars believe that saliva, as the external environment of teeth, is an important factor affecting dental caries.
1. bacteria
And the development of dental caries, because bacteria play a leading role in the etiology of dental caries and dental caries is recognized internationally in recent years many kinds of bacteria bacterial disease caused by caries, the most important is some mutans streptococci and lactobacilli. These bacteria are mixed with mucin and food debris in saliva and firmly adhere to the surface of the tooth and the pit. This adhesive is called plaque or plaque (dental, plaque). A large number of bacteria producing acid in plaque, resulting in decalcification and dissolution of the enamel surface below plaque. Clinical investigation showed that children with more plaque in the oral cavity also had more caries.
2. diet
Diet is an important part of bacteria during dental caries formation. Contains large amounts of carbohydrates and sugars in food, bacterial life and activity energy of these substances can supply the plaque, and the bacterial metabolism of the glycolysis to produce organic acid, acid lingering on the teeth surface and fissure, the enamel demineralization after damage, some bacteria and dissolved protein formation of cavity. There are many kinds of cariogenic sugar, and the most important one is sucrose.
At the time of tooth development, nutrition determines the biochemical structure of the tooth tissue, calcification, good teeth, high caries resistance. If the food contains mineral salts, major vitamins and trace elements, such as calcium, phosphorus, vitamin B1, D and fluoride and so on, the dental caries resistance is low, resulting in caries conditions. The development and calcification of deciduous teeth during the fetal period, while the nutrition of the mother's new milk stage has no decisive influence on the development of the primary teeth, but strengthening the maternal nutrition is still beneficial to the calcification of the deciduous teeth. Unless the mother is suffering from severe metabolic disorder or inherited disease, it is unlikely that the primary teeth will be seriously affected.
3. teeth
The morphology, structure and location of teeth are closely related to caries. The defects in the development of the tooth bite surface are the retention of cells and food debris in the deep fossa, and it is difficult to remove and cause caries. Lack of mineralization, especially in the teeth with insufficient calcification, the density of the enamel and dentin is not high, the resistance to caries is low, and it is prone to caries. The content of fluoride in the teeth of the mineralized structure although very few, but it is very important to enhance the anti caries of teeth. Dental fluorosis is difficult to occur when there is adequate fluoride in the teeth. The structure and calcification degree of deciduous teeth and young permanent teeth are not mature enough, so they are susceptible to caries and have high caries rate.

Saliva is the external environment of the teeth, a buffer, washing, anti castor or bacteriostatic effect. A large amount of dilute saliva can wash the teeth and reduce the accumulation of bacteria and food debris. A small, thick saliva tends to hold up, contributing to plaque formation and adherence to the tooth surface. The nature and composition of saliva affect its buffering capacity, and also affect the living conditions of bacteria.
This article is to introduce some causes of dental caries, dental caries caused by a variety of reasons, mostly related to your diet, Xiao Bian here that readers, the harm of dental caries is very large, so the parents for the children of the future must do the work for prevention of dental caries of children.

Why are baby teeth more prone to dental caries?

Many parents find that babies begin to develop cavities on their baby teeth and find that most of the children around them also have decayed teeth. Parents will wonder why children's teeth are more susceptible to dental caries? Here we look at the reasons, and I hope to help you.
There are two reasons for this.
On the one hand, children with oral unclean, infants will not brush your teeth, gargle, older children can gargle, brush your teeth, but most of the children will be brushing mouthwash, not serious, can not adhere to the early and late brushing, mouthwash after eating, so in between teeth and fissure in the retention of food residue.

On the other hand, children like to eat snacks, especially candy, and even some children sleep with sugar in their mouths. We know that there are a lot of bacteria in the mouth, especially Lactobacillus, which can ferment sugar and food residue and produce a large amount of lactic acid, which can destroy the structure of teeth and cause dental caries. On the other hand, the children's nutrition condition is not good, such as the children suffering from malnutrition, rickets and various chronic diseases, especially in patients with vitamin D deficiency rickets in children, due to lack of teeth calcium, teeth loose structure, more easily the formation of dental caries lactic acid erosion.
Above to introduce the children are more prone to cause dental caries of deciduous teeth, parents should be more attention for the prevention of dental caries of children. The children suffering from dental caries are mostly caused by the impact of bad habits, if it is found that the children had caries, he must go with timely treatment.
