Etiology and prevention of dental caries in children

Caries is a common oral disease, the incidence of high incidence in children, that is, people often say that the long "insect teeth." Children's dental caries generally damage the deciduous teeth, but not timely treatment will give the future development of permanent teeth adversely affected. So what is the cause of the child's tooth decay? How to prevent it?

The cause of tooth decay is plaque
The main cause of dental caries is plaque. Dental plaque is a layer of almost no color on the surface of the film, containing bacteria causing dental caries. After each meal, the plaque in the bacteria and food in the sugar or starch chemical action, resulting in corrosion of the teeth of acidic substances.
Over time, the enamel of the teeth will be destroyed, the formation of relatively fragile small spot, if the continued deterioration will form a tooth hole, that is, tooth decay. Therefore, the tooth decay is developed from the small spot, not really have borers or any other insects, but the teeth are gradually corroded results. Tooth decay in severe cases, can cause tooth necrosis and fall off.
Children often drink yogurt can prevent tooth decay
A new study in Japan found that regular yogurt can reduce the risk of children suffering from tooth decay. 3-year-old children who eat at least 4 times a week of dairy products can reduce the risk of tooth decay by 22% compared with children who eat less than once a week.
The reason why yogurt reduces the risk of tooth decay is still unclear, but one argument is that yogurt contains protein, the protein attached to the tooth surface to prevent harmful acid attack teeth, it also means that the composition of dental enamel calcium and phosphate will not break down. Australian scientists put the unplugged teeth into yogurt and found that yogurt can prevent dental cavities.
This article for everyone to introduce the cause and prevention of dental caries, experts advise you parents, although often drink yogurt can prevent children's tooth decay, but for the protection of children's dental health should pay more attention to the child's oral hygiene, to gradually develop children to form a good brushing habits The

What are the causes of dental caries?

Children in childhood like to eat candy, no attention to oral hygiene, slowly formed on the caries. Dental caries will directly affect our diet, but also affect the beauty of our teeth. Here, we through this article to understand what the reasons for the formation of dental caries.
Causes of dental caries:

In daily life, most people think that suffering from dental caries is due to too much sugar, in fact, this is only part of the reason, the cause of dental caries is very complex. The medical profession after long-term study that: dental caries is roughly by the four pathogenic factors together results. They are bacteria, food, teeth and time.
Specifically, there is a large number of bacteria in the mouth to survive, some of which bacteria such as Streptococcus mutans, actinomycetes, lactobacilli have the ability to produce harmful dental chemicals, the teeth are very hard, chewing food wear on it Consumption is very small, but these chemicals can be a short time to gradually break down the destruction. Therefore, cariogenic bacteria on the formation of dental caries is essential. 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 sugar substances in the food. Food on the teeth like a double-edged sword, on the one hand, the food supply to the body to nutrition, so that the teeth more solid, and enhance the caries resistance of the teeth; the other hand, the food contains carbohydrate chewing swallow, part of the remaining Oral, the use of cariogenic bacteria, resulting in corrosive substances on the teeth, thereby breaking the hard tissue of the teeth, which led to the occurrence of dental caries.
Teeth are very hard, but due to genetic, nutritional and other factors led to the development of different levels of calcification in the teeth, the degree of tooth calcification is low, the tooth surface uneven, enamel layer is relatively weak, easy to be destroyed; Irregular, easy residue of food residues, but also susceptible to dental caries.
The last factor is time, cariogenic bacteria use of food residues in the synthesis of destructive substances need a certain amount of time, all of these four factors together to cause the occurrence of dental caries. Therefore, the prevention of dental caries from these four aspects to start. After the occurrence of dental caries is not static, once the bacteria in the tooth surface to open a breakthrough, it will quickly spread to the teeth deep, further damage the hard tissue of the teeth, leading to pulpitis and even apical perioditis and other diseases.
Through this article we understand the reasons for the formation of dental caries, which we prevent and protect the teeth have an important reference. The occurrence of dental caries directly affect our health, so to attract our attention, do the relevant protective work.

What are the effects of dietary factors on dental caries?

Caries is a bacterial disease, not only the caries itself will cause harm to patients, it may also induce other oral diseases or inflammation. If there is a dental caries without timely treatment, may be infected with other teeth. The following talk about diet factors on dental caries have any effect.

The occurrence of dental caries and diet factors
Food is often in contact with enamel surface, can be used as a substrate for caries microorganisms directly affect the occurrence of dental caries. The relationship between food and the incidence of dental caries is very close, different food because of its nature, type and cooking methods are different, caries ability is also very different. The dietary factors that are closely related to the occurrence of dental caries are as follows:
Carbohydrate The most likely caries are monosaccharides and disaccharides, such as glucose, sucrose and so on. They are the substrate of cariogenic bacteria metabolism, for the survival of bacteria provides a wealth of nutrients, its metabolites can cause tooth damage. Pure sugar food carbohydrate caries in the strongest, sticky soft candy, cakes and other easy in the teeth gap or ditch nest deposited down, but also easy to cause dental caries. The acid-producing ability of various carbohydrates is positively correlated with cariogenic activity, and the order of strong to weak is sucrose, glucose, maltose, lactose, fructose, sorbitol and xylitol.
2. Dietary fiber. Dietary fiber protects teeth from dental caries. Dietary fiber can enhance the self-cleaning effect of the mouth, remove the food residue attached to the tooth gap, and itself should not be attached to the tooth surface, can greatly reduce the chance of suffering from dental caries.
3. Fluoride. The level of fluoride in drinking water, the impact of dental caries and plaque formation. Fluoride acts as an anti-caries by enhancing the acidity of tooth enamel and inhibiting the growth of eosinophils.
4. Food properties. Regular consumption of non-cooked or rough food is generally lower than the consumption of fine, fine, soft, sticky food, which is the physical properties of food and chemical composition by the close relationship.
Four kinds of Chinese medicine to prevent dental caries
Magnolia: there is temperature, the next gas, dampness, phlegm function, attending stomach food, phlegm cough cough, cold dampness diarrhea, toxicity, the main cariogenic bacteria Streptococcus mutans have the ability to inhibit.
Gallbladder, blood in the stool, carbuncle swollen sore, skin wet rotten, non-toxic, gallnut has a good inhibition of the role of cariogenic virulence factors.
Tea polyphenols: the main components of tea, especially from green tea extracted polyphenols, antioxidant and free radical scavenging function, with broad spectrum and strong antibacterial effect and the advantages of low YAO concentration.
Propolis: from the workers in the nest nesting honey in the process of sticky secretions and plants in the gum, resin and beeswax and other substances mixed with Streptococcus bacillus have inhibitory capacity, and anti-inflammatory, and promote tissue regeneration.
       Above for everyone to introduce the diet factors on dental caries have any effect, we understand the correct diet can prevent the occurrence of dental caries, the wrong diet may induce dental caries. Therefore, we should eat less harmful food on the teeth, you can also use the above four kinds of Chinese medicine to prevent dental caries.

What is the relationship between dental caries and dentin

The incidence of dental caries is becoming more and more widespread and the incidence is getting higher and higher. It has not only a direct relationship with our usual oral hygiene, but also a very important factor in the occurrence of this disease, that is, the quality of the teeth. Teeth good, you can very good to prevent dental caries. So what exactly are they going to do?
(1) nutritional status: refers to the food through the gastrointestinal digestion and absorption and the use of the human body, the growth and development of the teeth and nutrition.

If the lack of nutrition or lack of a direct impact on the quality of the tooth structure. Such as human embryos 92 days, deciduous teeth began to develop, to 194 days, enamel and dentin has been formed. If the human embryonic period, the teeth began to grow and develop, because pregnant women suffering from a systemic disease, causing malnutrition or nutritional disorders, can affect the normal development of fetal teeth.
① lack of vitamin A in the body, the impact of enamel cell function, resulting in enamel hypoplasia, leading to decreased dental caries resistance.
② body vitamin B6 deficiency, increase the chance of dental caries.
③ tooth formation process, for some reason caused by lack of protein in the body, may cause tooth formation defects, increase the sensitivity of dental caries. The above findings were confirmed in animal models. Also confirmed that the lack of protein, can cause larval salivary gland development deformities, indirectly, to promote the occurrence of dental caries.
(2) minerals: the body of various mineral content is also related to the occurrence of dental caries.
① fluoride: the formation of indispensable teeth of the material. Fluoride through the systemic and local effects, reduce the incidence of dental caries. After tooth eruption, the use of fluoride toothpaste or fluoride drugs brushing or smear, can increase the ability of dental caries. Because fluoride and enamel chemical reaction, can reduce the sensitivity of the teeth on the caries. Fluoride drugs in the early enamel caries, can promote the re-mineralization of caries.
② phosphorus, calcium, vitamin D: dental calcification can not be open phosphorus, calcium and vitamin D. Lack of these substances, affecting the normal development of enamel, can cause enamel hypoplasia. Enamel hypoplasia, increased susceptibility to caries. Maintain the intake of trace elements, can reduce the risk of dental caries.
This article for everyone in detail the relationship between the presence of dental caries and dentition, in summary, the production of dental caries and dentin are closely related, therefore, we must pay attention to the diet in the nutritional supplement, keep healthy teeth , But also pay attention to the clean mouth.

What are the factors that cause dental caries?

Caries is invading our lives, dental caries is a chronic disease, but also a bacterial infection, we have to bacteria, food, host, time these four aspects to prevent dental caries. Protect our teeth, smile face every day. So, the following for everyone to tell us about the factors that lead to dental caries.
One, bacteria

People's mouth is a huge bacterial library, these bacteria are mostly conditional pathogens, if the oral environment is clean, they will not be pathogenic, if the oral cavity often stuck caries food, it will form plaque on the surface of the teeth, Bacteria mainly with plaque adhesion to the tooth surface, dental plaque is the bacteria in the tooth surface of the caries an important environment, with such an environment, the original conditional bacteria become a pathogen.
It is generally believed that there are two types of cariogenic bacteria, one is the acid bacteria, mainly Streptococcus mutans, actinomycetes and Lactobacillus, carbohydrate decomposition can produce acid, resulting in tooth mineralization demineralization; another Species is Gram-positive cocci, can damage organic matter, after a long period of time can make teeth forming cavities.
Second, food
Mainly carbohydrate foods such as sucrose, glucose and refined rice noodles. Bacteria can use sugar to produce acid and corrosion of teeth. Sugar can promote the adhesion and accumulation of bacteria in the tooth surface, and for the growth of bacteria, metabolism to provide nutrition. Therefore, sugar and carbohydrates are the basis of the occurrence of caries.
Third, the host
Mainly refers to two aspects. One refers to the body's physical condition, immune function, oral health is good, is not conducive to the survival and reproduction of bacteria.
Second refers to the quality of the teeth, including the shape and structure of the teeth. Teeth itself is not calcified, poor surface finish, irregular arrangement of teeth, crowded, overlapping, etc., are conducive to bacterial and food residues, susceptible to caries. Others such as inheritance, nutrition, minerals, endocrine on the host's anti-caries also have an impact.
Four time
"Frozen three feet, not a day of cold", from the initial caries to the clinical formation of cavities generally need 1.5 to 2 years, divided into three stages.
The first stage of the caries stage, due to lesions mainly damage enamel, also known as enamel caries. Mainly for the surface of the teeth by the smooth and rough, carious parts of the color becomes dark or dark brown or tooth surface fissure black.
The second stage, said the caries stage, lesions dentin shallow, also known as dentin caries, due to dentin destruction, began to form shallow cavities, cold, hot, sweet, sour food feel sore, when stimulated After removal, the symptoms disappear.
The third stage, said deep caries stage, lesions have reached the dentin deep, also known as dentin deep caries. Due to deepening the expansion of teeth to expand the formation of deeper cavities. When the bacteria and their metabolites through the cavities into the pulp caused by pulpitis, the occurrence of abscess or severe pain.
Above for everyone in detail the factors leading to dental caries, dental caries will not occur within a short time, even if all factors exist at the same time, it will take a long time before it can form dental caries. So the time factor in the occurrence of dental caries is of great significance, early treatment of early rehabilitation.

The most likely to have dental caries oral parts

Caries often appear in everyone's life, it is a wide range of disease, to bring a lot of life disorders, serious impact on oral health. In fact, different oral parts of the risk of dental caries are different. Here, with everyone to understand, that part of the most vulnerable to dental caries.
(1) two teeth adjacent to the tooth surface susceptible to caries. Under normal circumstances, the gums are filled with tooth gaps, so that the adjacent teeth are protected from caries.

Solution: brush your teeth should pay special attention to clean the teeth adjacent to the teeth can also be used to clean up the adjacent teeth to prevent the occurrence of adjacent caries.
(2) irregular arrangement of teeth, such as teeth twist, overlap, tilt, elongation, etc., poor contact between the teeth, brushing is not easy to brush clean, easy to accumulate food residues, bacteria in this breeding, the formation of dental caries.
Solution: Therefore, for children of the dentition of the child, parents should promptly take the child to the hospital to check the treatment, in the correction of dentition deformity at the same time on the prevention of dental caries also have some positive significance.
(3) the posterior teeth occlusal surface has a lot of nest, ditch, cracks, these parts of the deep, is the tooth development and mineralization period left the defect, the conventional brushing mouthwash is not easy to keep clean, so easy to cause food debris Residue and bacterial reproduction, is the most likely place for dental caries.
Solution: In addition to the usual attention to the cleaning of these parts, but also by just eruption of the early molar for the early pit and fissure closed, can prevent the occurrence of pit and fissure caries.
(4) the old teeth of the neck is also susceptible to caries, it is because the general situation, the elderly periodontal atrophy, tooth exposure, in the anatomy of the site is a weak area, if the brushing method improper (horizontal brushing) So that the normal tooth tissue defects, it is easier to form dental caries.
Solution: should use the correct brushing method, and pay attention to clean the teeth neck, active treatment of periodontal disease.
(5) mandibular wisdom teeth mass, near the direction of the tilt, often the second molar in the far adjacent to the occurrence of dental caries. For the location is not enough, wisdom teeth can not be completely erupted should be early removal.
(6) The above is the location of dental caries, and the teeth of the tongue and mouth, the tip of the teeth and teeth are not only smooth, but also by chewing, tongue movement and saliva rinse, food residues and bacteria Not easy to stay, so it is not easy to occur dental caries.
This article for everyone in detail the most likely to suffer from dental caries oral areas, warm Tip: We must adhere to brush your teeth in life, to ensure that every part of the teeth must be clean, to prevent the incidence of dental caries. Toothbrush must use the soft hair, reduce the harm to the gums.

What is the cause of dental caries?

At present, as people now improve the living standards, eat more types of things, but also more messy, and dental problems have come. One of the most important questions is dental caries. Now there are a lot of people suffering from dental caries, from children to adults, that in the end what is the cause of it? Let's look at the expert's explanation.
The currently recognized theory of dental caries etiology is a quadruple factor theory, mainly including bacteria, oral environment, host and time, the basic point is: 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, 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 dental caries disease 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 occurrence of dental caries.
(2) saliva in the normal circumstances, saliva has the following effects:
A mechanical cleaning to reduce the accumulation of bacteria.
B antibacterial effect of direct antibacterial or inhibition of plaque attached to the tooth surface, to prevent the occurrence of dental caries.
C anti-acid effect by the heavy bicarbonate and other substances from the role of neutralization.
D anti-soluble role 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 dental caries.
3. host
Teeth is the target organ during the process of dental caries. The shape of the tooth, the degree of mineralization and the structure of the tooth are directly related to the occurrence of dental caries, such as the fissure of the teeth and the poorly conceived teeth, 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 dental caries.
Time
The occurrence of dental caries 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 disease 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.
Although the number of people suffering from dental caries every year showed an increasing trend, but the dental caries did not cause enough attention, there have been reports that seventy percent of the sick did not go to the hospital to do the check, to remind We must go to the hospital as soon as possible, so as to avoid serious consequences.

How is dental caries formed

Dental caries is often a disease, once unfortunately suffering from dental caries will be particularly painful. Here are some of the reasons for the formation of cavities, hoping through the above description can help you better understand the dental caries of this disease, only a clear understanding of the disease in order to be able to do a better life in the prevention of work.

1: bacteria: the presence of bacteria is the main condition of 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 the formation of plaque, thus controlling the occurrence of dental caries.
2: food: edible rough food has a certain self-cleaning anti-caries, eating rough food is not easy to produce more plaque and accumulation of more acid, which is not easy 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 in the tooth surface stay longer, the hard tissue of the teeth dissolved And produce caries.
3: 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 prone to caries. Saliva has the effect of cleaning teeth, saliva of certain ingredients on dental caries and periodontal disease can play a role in inhibiting.
4: time. The occurrence and development of caries is a rather slow process, the time it takes for carbohydrates to remain on the tooth surface, the time required for tooth eruption, and the time from plaque formation to caries, An important factor in the disease.
Above is for everyone to introduce the cavities of several ways, I believe that through the introduction of the above for the dental caries this disease has a relatively deep understanding of the hope that the above description of your life in the prevention can help, As long as the usual life in the attention to avoid the occurrence of several cases can be effective in preventing the occurrence of dental caries.

What is the cause of dental caries in early childhood

Dental caries is a relatively common oral disease, almost everyone has suffered from the disease experience, and even many people from infants and young children have been suffering from dental caries, why infants and young children prone to dental caries it? This is what everyone wants to know the answer to the question. Please ask the following oral experts for us to do a detailed answer!
From childhood to develop good oral hygiene habits

Children about 2 years old, most of the deciduous teeth have grown, and deciduous teeth occupy the position of permanent teeth, deciduous teeth damage is likely to lead to the development of permanent teeth problems. At this point should take the child to do the first oral examination.
Experts pointed out that parents should start from childhood to develop children to develop good oral hygiene habits, which include twice a year to see a dentist. Early to take the child to see the dentist, not only can understand the child's deciduous teeth is healthy, but also allow children to learn from the dentist to brush your teeth the right way.
Early childhood, especially need to pay attention to dental caries
Early childhood is a sensitive period of dental caries, susceptible to disease and rapid development. "5-year-old children, for example, dental caries rate of 66%, per capita rotten teeth." Experts pointed out that lead to children prone to dental caries for three reasons.
1, deciduous teeth enamel and dentin thin, low degree of calcification, acid resistance is weak, and thus easier to decalcinate than the permanent teeth;
2, children often eat soft and high sugar foods (such as sweet milk, cakes, beverages, etc.), easy to ferment acid, long-term adhesion to the teeth and easy to caries;
3, many parents do not attach importance to the child's deciduous teeth health care, that child deciduous teeth anyway to change, even if the child is not for the treatment of rotten teeth.
Experts remind that the child rotten teeth is not timely make up easily lead to infection, causing local inflammation, swelling and pain; tooth pain will reduce the chewing function, affecting the absorption of nutrients, resulting in child growth and development. Deciduous teeth for a long time, the future will affect the arrangement of permanent teeth, resulting in permanent teeth are not neat. He advises parents to urge their children to do the following to reduce the incidence of dental caries
1, to reduce the intake of sweets and snacks, eat something to be timely mouthwash.
2, correct brushing, effective brushing teeth. If you use ordinary toothbrush, each time to brush your teeth must be guaranteed 3 minutes, with electric toothbrush brush for 2 minutes. Brush your teeth but also exhaustive, inside and outside have to brush clean. Clinical examination found that, due to the reasons for not easy, most children on the right side of the teeth are dirty.
3, the child about 7 years old, to "six age teeth" do pit and fissure closed.
Above for the parents in detail the introduction of early childhood dental caries for a variety of reasons, and now, for early childhood prone to dental caries, whether you have a certain understanding of it? Xiaobian to remind you that life must pay attention to baby oral hygiene, in order to stay away from dental caries hazards.

How does dental work occur?

As we all know, the problem of teeth, in fact, not the naked eye can see the insects, in fact, it is not caused by a cause but by other causes caused by many other people want to know is the dental carving 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 conditions 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 in the tooth surface stay 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 the formation of plaque, 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 prone to caries. Saliva has the effect 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 carbohydrates to remain on the tooth surface, the time required for tooth eruption, 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 treat as soon as possible, so as not to give your life with the inconvenience of trouble! You would like more about dental caries related diseases, you can continue to browse the questionable network to find the answer you want to know.

Why the elderly will suffer from dental caries

We all know that old teeth is 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 lead to teeth can not be normal chewing food, is not the proportion of elderly patients with dental caries? Why old age suffering from dental caries?
1. Saliva secretion reasons:

Elderly due to salivary gland function decline. Alveolar bone and gingival atrophy, increased interdental space, food impaction increased, the normal physiological environment of the mouth was gradually destroyed. Oral self-purification effect decreased. Salivary gland secretion of lysozyme content is also low, oral bactericidal ability decreased, so the caries can be a large number of elderly dental caries to breed, resulting in 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 cariousness: refined sugar in the oral bacteria involved in the fermentation products, under the appropriate conditions (temperature, humidity, stay in a certain location), for the tooth hard tissue gradually play decalcified dissolved The role of, causing dental caries.
3. Texture itself Cause:
The body of the hard tissue of the body's physical metabolism decreased, 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 stove, 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 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, good for the teeth. 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 acid.
However, the bacteria in the mouth can make the 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, and not because of the slow dissolution caused by osteoporosis, so the medicine is often used to repair the 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. Human blood and tissue also contain a very small amount of fluoride. Can promote wound healing, intestinal absorption of iron, to help nerve conduction and some of the enzyme metabolism.
In 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 food and rough 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 caries generally more diet, with people's habits are also related to fluoride is good for the teeth, so we should eat some of the food to keep the teeth healthy.

What are the factors that induce dental caries?

Caries is a common oral disease in infants and young children, dental caries do not deal with the possibility of pulpitis may cause, and will give the child a certain impact on the appearance. For the child's physical and mental health, be sure to do the prevention of dental caries. So, what are the factors that induce dental caries? To understand the predisposing factors of dental caries, will play a role in the prevention and treatment of dental caries.
What are the factors that cause dental caries?

1, the amount of saliva decreased or insufficient to induce dental caries. Saliva which contains a certain amount of anti-caries role of bicarbonate and calcium, phosphorus, fluoride and antibacterial substances. A lot of thin saliva on the tooth surface washing effect, and a small amount of sticky saliva easy to stay, is conducive to the breeding of bacteria.
2, systemic factors: vitamins A, C, D, minerals, calcium, phosphorus, trace elements such as fluoride, are the formation of dental raw materials, the human body if the lack of certain long-term nutrients, tend to increase the chance of suffering from dental caries. Long-term iron deficiency, calcium, phosphorus, often increase the susceptibility of caries disease, more susceptible to dental caries.
3, poor oral environment: the teeth of the oral environment, including saliva, cleanliness, diet and so on. These aspects of the problem, is an important cause of dental caries.
4, ignore the oral health susceptible to dental caries: dental caries and whether to maintain the relationship between oral hygiene is extremely close. Because the bacteria within the mouth will be food or beverage residues as a medium for a large number of breeding, tooth damage, the occurrence of dental caries.
5, the tooth structure defects: the most likely to occur in the teeth of the cave and cleft fissure, enamel calcification and poor structure of the glaze structure, because it is conducive to the breeding of bacteria; deciduous teeth calcification than the permanent teeth, Deep, poor contact with the neck, it is prone to dental caries.
6, the reasons for dental caries, often eat soft food can reduce the chewing effect, resulting in poor jaw development, dentition missing, is conducive to food and bacteria hidden, induced tooth decay occurred.
Above for a detailed description of the factors that induce dental caries, after reading the introduction of this article, for the cause of dental caries we should have a clear understanding of the factors. After understanding the cause, the following can carry out prevention and control work, so as to ensure the child's oral health.

Why children are so susceptible to dental caries

Dental caries commonly known as tooth decay, dental caries are not treated in time, the cavities will develop toward the depths, so that the formation of periodontal disease or pulpitis. People of any age have the possibility of dental caries, but children are more susceptible to the disease, which is why? Please ask the experts for a detailed answer.
Why are children so susceptible to dental caries?

This is because the children eat soft food on the one hand, such as all kinds of pastries, biscuits, candy and other snacks, such foods contain high sugar content, sticky, sticky to the tooth surface is not easy to clean, easy to form plaque, And thus become a breeding ground for bacteria, some children like to drink fruit juice, cola drinks, they are more sugar and high acidity, to the occurrence of dental caries to create favorable conditions. At the same time children eat less fiber foods, can not chew the food when the friction on the surface of the teeth automatically clean.
On the other hand children from 6 months to 2 years and a half is the stage of eruption, from 6 to 12 years old is the era of permanent teeth eruption of deciduous teeth, just eruption of the teeth development is not perfect, low degree of calcification, acid resistance is poor, And thus more easily corroded. The milk teeth, that is, we usually say that the teeth, but also has a tooth surface pit and fissure, adjacent teeth between the contact area is easy to accumulate food characteristics, these are children susceptible to dental caries conditions. Especially the thickness of the hard tissue of the teeth only 2mm, dental caries is easy to enter the deep teeth, so deciduous teeth once the occurrence of dental caries, progress quickly.
In addition, the child's oral health status also has an important impact on the occurrence of dental caries. When the child is very young, he will not brush his teeth, many parents are accustomed to bedtime to the children to drink milk or eat some snacks, but did not expect to help children (children's food) after cleaning teeth. And then more children sleep more sleep when the secretion of saliva reduced, the mouth is still in a state of rest, is not conducive to the cleaning of the teeth, which have increased the chance of suffering from dental caries.
Therefore, from the beginning of the teeth erupted parents should be patient every day to help children clean their mouths. Children 3 years old after the parents want to teach their own teeth, to develop a good habit of carefully brushing every day, to prevent the occurrence of dental caries is very important.
Above from all aspects to introduce the reasons for the emergence of dental caries in children, and now why children are so easy to suffer from dental caries, you have not found a clear answer to it? We remind you parents must pay attention to the life of the child's dental caries prevention.

Will lead to children suffering from dental caries snacks

Most of the children like to eat snacks, this is no way to change the facts. There may be no way for children to eat snacks, but parents can control the number of children eating snacks, snacks eat more may cause dental caries, the amount of eating some snacks, and do oral care is to avoid suffering from dental caries.

Commissioned by the Ministry of Health, China CDC Center for Nutrition and Food Safety and the Chinese Nutrition Society jointly prepared the "Chinese children and adolescents snack consumption guide" come out. The guidelines point out that sugar in overly sweet snacks is likely to cause dental caries, and most cereal snacks contain sugar and fat, which can be fermented to become acidic due to oral bacteria. Sugary drinks, such as carbonated beverages, fruity drinks and other sugar content, high energy, long-term or excessive consumption will increase the risk of suffering from caries, overweight and obesity.
"The sugar in the food residue in the tooth surface, easy to acid corrosion of the teeth, but also become the oral bacteria of the medium, so that plaque in the oral reproduction, resulting in dental caries." Zhang said that sugar is divided into monosaccharides, Polysaccharides, monosaccharides are mainly glucose and fructose, sucrose is disaccharide, cereal carbohydrate foods contain polysaccharides, these foods are easy to produce acid corrosion teeth.
       So eat snacks should be timely mouthwash or brush your teeth, to prevent the occurrence of dental caries. Children also pay attention to develop the habit of not eating snacks before going to bed, so as not to affect the health of the stomach and teeth.
Carbonated beverages and other beverages are added sweeteners, sugar and carbon dioxide, they are acidic. The teeth of calcium, phosphorus and other major components in the acid environment, will be free from the tuberculosis state, easy to cause corrosion of teeth, the formation of dental caries.
       Above for a detailed description of the various can induce dental caries snacks, we should know which snacks can not let the children eat it In addition Xiaobian to remind you, if you find a child with dental caries, be sure to take the child as soon as possible to the dental hospital for treatment, if the treatment may cause the child will cause more harm.
