What is the cause of dental caries?

Dental caries is often said cavities, or cavities, most cases are due to the infection factors factors, of course, is the most common bacterial infections, the incidence of dental caries, actually has a very close contact, and oral hygiene of course, bacteria are also different, such as Streptococcus, actinomyces, the etiology of dental caries introduction:
1, bacteria
The 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 organic matter, after 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.

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 prevention of oral saliva on dental caries has a great role in the presence of saliva can sterilization, cleaning and bacteria, that is to say, the saliva under normal circumstances, the role is to protect, but if it is unable to maintain normal levels in saliva, also can appear to cause disease.

What is the cause of dental caries?

Another name is tooth decay, is usually caused by bacterial infection, in life we know that regular consumption of foods which contain sugar will decay, in fact, mainly refers to the sugar food stuck in the teeth, causing infection in the bacterial invasion and the formation of dental caries, the etiology of dental caries were introduced:
1, bacteria
The 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 organic matter, after long-term effect can make the tooth formation of cavity.

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. 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 acid produced was beneficial to the production of acid and acid resistant bacteria, also is 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.

Can say, the cause of dental caries, and is actually a bacterial infection caused by, rather than eating sugary food and lead, in addition, saliva actually has a protective effect on oral cavity, can kill bacteria, as well as a large number of breeding bacteria, but if it exceeds a certain limit, naturally lose their effect.

What are the causes of dental caries?

The key factors for the incidence of dental caries is a bacterial infection, and people's saliva itself has the function of protecting teeth, but it refers to the situation in normal saliva, and if it is caused by the amount of saliva, and cause changes, will cause the cause of dental caries, the following specific introduction on the risk factors of dental caries:
First of all, the presence of bacteria is the main condition for caries. Plaque is an important environment where bacteria produce caries on the tooth surface. The quality of oral hygiene is also the condition of caries. Good oral hygiene controls the formation of plaque and controls the occurrence of dental caries.
Two is food. Eating crude food has a certain self-cleaning, anti caries role, eating rough food is not easy to produce a more abundant plaque and accumulation of more acid, so it is difficult to form conditions for caries. While the content of sucrose in food coarse food refining, sugar into the plaque, plaque in cariogenic bacteria to ferment sugar, form a variety of acid, the acid to stay longer in the teeth, the tooth hard tissue dissolution damage caused by dental caries. Eating sweets is more harmful during the period of tooth development, between two meals and before bedtime.

Three is the host. The host refers to the susceptibility to caries, and the susceptibility of the host to caries involves many factors, such as the velocity, flow, composition, morphology and structure of the saliva, and the general condition of the body. Irregular arrangement of teeth, crowded, overlapping places, susceptible to caries. Saliva has the function of cleaning teeth, and certain components of saliva can inhibit tooth decay and periodontal disease. Others, such as heredity, nutrition, minerals and endocrine, have a certain influence on the host's resistance to caries.
Four is time. The occurrence and development of dental caries is a very slow process, carbohydrate retention required for tooth surface of the teeth out of time, time, adorable plaque required from the formation to have the cariogenicity of time required, are important factors that influence the incidence of dental caries.
The cause of dental caries in children, the most important point is the lack of awareness of parents, because the children did not understand, self-control is relatively weak, therefore, in the prevention of dental caries in children, parents need to have sufficient awareness of the prevention, and grasp some key aspects of prevention.

What is the etiology of dental caries?

Dental caries is the most common form of dental disease, which causes tooth decay and can cause serious damage to the teeth. If you suffer from dental caries, there is no timely treatment, then, dental caries will become more and more serious, leading to a big hole in the teeth. So, what do you know about the cause of dental caries? People who don't know, take a look at the introduction of this article.
Three major causes of dental caries:

(-): the main reason of microbial dental caries of microorganisms belonging to the genus Lactobacillus (Lactobacillus), Streptococcus and Actinomyces and acid producing bacteria, and they can function in the oral cavity and the monosaccharide acid production, the effect of dental caries and plaque formation.
(two) dietary reasons: food is often contacted with the surface of enamel, and can be used as the substrate of cariogenic microorganisms to directly affect the process of dental caries. The etiology of food and dental caries is very close. Different foods have different caries ability because of their nature, kind and cooking methods.
(three) host reason: the main cause of caries is the tooth itself and saliva. Where there is the formation of retention area, prone to caries. The irregular shape of the arch and the crowding of the teeth all lead to dental caries. The teeth with calcification are not susceptible to caries. The higher the fluoride and zinc content in the enamel, the lower the incidence of caries. Changes in saliva mass and volume, buffering capacity, and changes in the antimicrobial system all affect caries.
The above content for everyone to introduce what causes caries, many people suffer from dental caries, but also know what causes it. I hope the above can help you find out the cause of your dental caries. If you want to avoid caries, you need special attention in your daily diet and oral care.

Which teeth are prone to decay?

Although there are many people who have decayed teeth in the impression, most of them are children, but in fact, many adults don't pay attention to diet and oral care, which results in the occurrence of dental caries. For dental caries, in fact, we still know less, for example, you know which teeth are prone to caries?
Two teeth adjacent to the tooth surface susceptible to caries. Under normal circumstances, the gingival papilla is full of tooth space, so that the adjacent surface of the tooth is protected, not susceptible to caries. However, as age increases, the chewing movement causes adjacent wear, loss of normal contact with the teeth, or periodontal disease leading to periodontal atrophy. At this time, teeth exposed, two teeth adjacent teeth food residue, self-cleaning effect of poor teeth, easy to cause the bacteria to multiply. The metabolism of bacteria produces acid, resulting in the demineralization of tooth enamel and other hard tissues.

Irregular arrangement of teeth, teeth such as torsion, overlap, tilt, elongation, tooth contact between Su bad, when brushing your teeth is not easy to clean, easy accumulation of food residues, bacteria in the breeding, the formation of dental caries.
There are many cracks, fossa, ditch posterior occlusal surface, these parts in the deeper, tooth developmental defects left mineralization period, regular tooth brushing gargle is not easy to keep clean, so easy to cause food debris and bacteria, is most likely to occur at the position of dental caries.
We should pay special attention to these teeth which are prone to decay, and should be especially careful when cleaning these areas. In daily life, we should minimize the intake of sugar and carbonated drinks. These foods are particularly vulnerable to tooth damage and are the major enemy of dental caries prevention!

How do dental caries develop?

Dental caries is a chronic disease, when most people in superficial caries, usually not how to treat, because this time there is no obvious pain, but in fact, this is not desirable, because will continue to develop. So what exactly is the formation of dental caries? In adolescents, dental caries is a kind of disease, but also teenagers to bring some pain, so after the occurrence of dental caries will appear in what situation? Let us look down.
The cause of dental caries is the result of the influence of various internal and external factors. In recent years, with the development of medicine, the etiology of dental caries has been further explained. It is believed that dental caries is caused by the coexistence of three factors, namely bacteria, carbohydrate, food and the anti caries ability of teeth.
The role of oral bacteria. Streptococcus mutans and lactic acid bacteria in the mouth reproduce on food residues remaining in the mouth, which ferment and produce acid, which causes the teeth to corrode, soften, and decalcification. When the tooth is decalcified, it gradually forms a cavity.
Sugar is a necessary condition for dental caries. Carbohydrates play a decisive role in the development of dental caries. Especially, foods containing sucrose can increase the number of plaque on the tooth surface and increase the number of cariogenic streptococci.
The body's resistance to caries has a significant impact. The body's resistance includes the teeth and the body's anti caries ability, the body's internal factors can affect the occurrence of dental caries. Especially when the protein, minerals and vitamins are scarce, it can help the occurrence of dental caries.
The morphology, structure, location, oral hygiene, quantity and nature of saliva, nutrition, endocrine, genetic factors, systemic diseases, immune status and so on all affect the occurrence and development of dental caries. The teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, teeth, and teeth. Saliva viscosity, quantity, oral health, endocrine disorders, malnutrition, tuberculosis and other systemic diseases, trace elements deficiency are related to the occurrence of dental caries.
After the tooth decay occurs, there is no uncomfortable feeling at the beginning, only a small hole in the tooth. When the decayed tooth grows deeper and close to the sensory nerve endings of the pulp, the cold, hot, sour, sweet food is sore. Serious when can cause pulpitis or root inflammation caused by severe pain.
Generally speaking, the following hazards exist:
1. when the caries destroys the enamel and invades the dentin, the patient feels pain when it meets cold, heat, acid and sweet stimulation. The clinical examination shows that the cavity is formed on the tooth and is dark brown. In this stage, if untreated, the decay will gradually increase the pulp, caused by pulpitis, then there may be spontaneous pain, can also cause ipsilateral headache, restlessness patients. If not treated, the inflammation continues to develop to the root direction caused by periapical root swelling, pain, loose teeth, bite periodontal pus, severe facial swelling, have a fever, trismus, bacteria into the blood can cause bacteremia and even life-threatening.
2. dental caries is not treated in time, can be gradually developed severe periapical, will cause dysplasia, if due to caries early loss of deciduous teeth and permanent teeth will not only affect the schedule that will lead to the adorable, permanent teeth arranged in disorder, caused by malocclusion.
Permanent teeth due to caries early loss, missing teeth number, will affect the chew food, will increase the burden on the stomach, causing gastrointestinal disease.
1., serious caries caused by crown, residual roots, stimulate the surrounding soft tissue, causing ulcers, erosions, and even cancer. Can also become a focus of bacteria, the base camp.
2., the toxin of bacteria can flow to all parts of the body. Data show: caries lesions can cause iris, ciliary body inflammation, rheumatoid arthritis, nephritis, rheumatic heart disease or viral myocarditis, systemic pain and so on.
So, to prevent the occurrence of dental caries, which items should be paid attention to?

First of all, we should pay attention to oral hygiene, learn the correct way to brush teeth, and develop good habits sooner or later brushing teeth and mouthwash after meals. Toothbrush can use health toothbrush and fluoride toothpaste. Trace elements of fluoride can resist the acid corrosion of teeth.
Secondly, do not eat too much sugar, but also pay attention to nutritional supplements and physical exercise, in order to enhance the ability of disease resistant bacteria invasion.
Finally, it should also be noted that routine oral examinations should be conducted regularly so as to detect dental caries in time and to repair it as soon as possible.
The correct way is: the toothbrush should be along the long axis of the tooth vertical brush, the brush on the teeth from the top down brush, brush teeth from the bottom up under the brush, brush on the occlusal surface, press the bristles on the teeth, brush back and forth, brush the outside brush inside.
The above description has a very detailed, we believe that the friends of patients should have a more profound understanding, for it is not against dental caries, a short duration of time things, at the same time, the formation of dental caries is not a short duration of time, in daily life, always pay attention to, take good care of their teeth, because no one think so early and some nice to say goodbye.

What are the factors causing caries?

At present, the incidence of dental caries is getting higher and higher, and the incidence is becoming more and more widespread. I believe that many people have experienced dental caries. So, do you know what factors lead to the onset of caries? In our daily life we all think of the tooth decay caused by too much sugar. In fact, there are four factors that cause caries, and they are indispensable.
1. bacteria
Bacteria are mainly by plaque adhesion to tooth retention oral carbohydrates were degraded to a high viscous dextran polymerization to form plaque matrix composition; on the other hand the acid producing tooth demineralization plaque is more complex in addition to a large number of bacteria and sugar protease substance.
2. oral environment
The oral cavity is the external environment of the teeth, which is closely related to the occurrence of caries. The main functions are the food and saliva
(1) the main food is the main energy in the formation of bacterial plaque bacteria is related with plaque matrix carbohydrate can use carbohydrates (sucrose) metabolism of organic acid and acid synthesis of extracellular polysaccharide and intracellular polysaccharide production.
(2) the amount of saliva and qualitative changes can affect the caries rate of clinically visible xerostomia or salivary secretion in patients with caries rate increased significantly in treatment of patients with maxillofacial radiology because salivary gland was destroyed and there are a number of dental caries; on the other hand, when the lactic acid in saliva increased or bicarbonate the content is also conducive to reduce caries.
3. host
Is the tooth form and organizational structure and the degree of mineralization of dental caries in target organs in the process of dental caries is directly related to occurrence of such teeth fissure and bad teeth mineralization are more susceptible to caries and better tissue containing fluorine degree of mineralization in the appropriate amount of dental caries resistance is strong; on the other hand the body structure and the teeth are closely related especially is the development and structure in development not only affects the teeth and flow velocity and composition of saliva also has a big impact because it is an important link in the occurrence of dental caries.

4. time
The incidence of dental caries is a long process from the beginning to the formation of the general clinical caries 1.5-2 years so that even if the cariogenic bacteria suitable environment and susceptible to caries exist at the same time will not immediately occur only these three factors also exist for a long time can cause caries so the time factor in the caries is important caries.
In this paper, we introduced what are the factors causing dental caries, dental caries caused by four factors are indispensable, their interaction leads to tooth decay, bring harm to patients, oral health in life so we must pay attention to oral hygiene, inhibit the breeding of bacteria.

What are the causes of caries in children?

I believe that most parents want to know what is going on children's dental caries susceptibility to the disease, although we have not unfamiliar, but people still do not pay attention, as well as to the children, because they think it will change teeth child, actually this is wrong. Now, let's see what the dentist says.
(1) when the tooth just eruption, the degree of calcification of the tooth is low, the surface is not smooth, and there are many pores, the acid resistance of this kind of tooth is bad, and the bacteria easily attach to the tooth surface to form plaque, so it is prone to decay.
(2) the beginning of adorable teeth, especially young permanent tooth occlusal surface groove, fossa, point gap and deep, easy to make food impaction stranded here, hidden bacteria, and brush your teeth, gargle is not easy to clean, so easy to caries.
(3) children's teeth chewing function is weak, eat soft food, which often contain a lot of sugar, easy to ferment and produce acid, and prone to dental caries.
(4) the children like to eat snacks, food is high in sugar, Huo thick and strong, soft and fine foods, such as cakes, bread, biscuits, candy, milk and other beverages are children love food. These foods due to the long spear easily attached to the surface to ferment and produce acid, erosion of teeth and dental caries.
(5) poor oral hygiene. Infants can not brush their teeth, most children brush their teeth, do not seriously, the method is not correct. Children are so young and ignorant that they almost have bad habits of eating good snacks and not cleaning their teeth. When the dentist asked the child every day, brush your teeth several times, each time brushing time, many parents said "brushing is as a mere formality, brushing more than thirty seconds", as short as a few seconds". This kind of bad habit of treating one's teeth is of course susceptible to decay.

(6) the sleeping time of the children is long, the oral cavity is still in sleep, the amount of saliva is reduced, the flow rate is low, and the mechanical function of saliva is decreased. Due to decreased secretion of saliva and saliva of some antimicrobial substances, lysozyme and other components and is conducive to reduce the amount of dental health, which is conducive to the breeding of bacteria and some bad habits of children, such as bedtime eat bread and pastries not brushing your teeth bad sleeping habits, some children are? Sugar, sleeping habits, and so on, so more likely to cause caries.
(7) parents often think that deciduous teeth are temporary, and they do not have much influence. Therefore, they do not pay enough attention to their children's dental caries and fail to treat them in time, which inevitably increases the development of caries.
The above is about children suffering from caries related factors, we should know something about it, I believe parents should know how to prevent children suffering from dental caries! We must not spoil our children, or let them form bad habits, which will easily cause them to suffer from decayed teeth.

What causes baby caries?

Now, dental caries is no stranger to us, because almost everyone has one or two decayed teeth. It affects our diet seriously. But why does the baby suffer from dental caries? The baby doesn't eat candy anymore, that's what most parents want to know. In fact, the baby's decayed teeth are caused by bad habits of parents.
Baby tooth decay source: parents have decayed teeth, children will give birth to full mouth cavity, which has become commonplace in real life, many people even think that tooth decay is hereditary.
Experts pointed out that the decay will not be inherited, but it will spread through the parents of the child's feeding behavior, such as children, which is one of the reasons children suffer from tooth decay. These harmful acts are as follows:
When feeding a baby with a bottle, the parents worry that the temperature is too high to hurt the child, so they suck on the nipple first.
Baby when feeding a baby tooth, his mouth chewing pulpy food spit out feed the baby to eat.

Kiss the child's mouth.
All of these actions can spread the disease causing microbes in the mouth to children. Parents develop cavities and children develop cavities. Experts stressed that parents should change in the bad habits of parenting, when kissing children, may wish to choose the face, forehead and other parts, the same can be carried out with the child emotional communication. In addition, we should strengthen publicity and education, so that children develop oral hygiene habits from childhood. Children can be scrubbed by their parents with soft towels or lint. After 3 years of age, children can start learning to brush their teeth, as far as possible, sooner or later each brush, mouthwash after meals.
Because the baby is too small, not to get something to eat, there is the most caries because parents do not pay attention to, the above is related to dental caries in children is associated with some bad habits of parents, parents have now learned! Therefore, we should pay attention to their own health, but also pay attention to the child's oral hygiene.

What are the factors causing dental caries?

The incidence of dental caries is getting higher and higher, and the incidence of the disease is becoming more and more widespread, which brings a lot of trouble to the patient's life. What is the cause of dental caries? Below, everyone will come to understand the cause of caries. Warm prompt: if you are a patient, please consult the experts as soon as possible, accept treatment, and wish you a speedy recovery.
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.

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.
The above content is today to introduce the etiology of dental caries, now we should know how the caries is it, if all of dental caries and other aspects of the problems and opinions, please consult your dentist experts, get more knowledge about dental caries.

What is the cause of dental caries?

What are the causes of dental caries? I believe this is a problem that many people are concerned about. Because most people are now bothered by this problem. Dental caries does not only affect our diet, but if it is serious, it affects all of our health. In order to avoid this situation, we need to know something about the cause of dental caries.
And the development of dental caries in 1. bacteria, because bacteria plays 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.

2. diet in the formation of dental caries, diet is an important role in bacteria. 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.
3. the morphology, structure and location of tooth and tooth have obvious relation with 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.

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.
The above is about the cause of caries related presentations, and now we should understand the causes of caries, we can be based on these causes to prevent. However, if there is caries, we must timely treatment, so as to avoid it seriously affect our health.

What's the cause of bad breath?

Bad breath is one thing is really embarrassing for us, because we will always communicate with others, but because of the reason of halitosis embarrassing for us to communicate with people, because of a mouth is easy to smell, use a variety of methods also don't know how to get rid of, then what is the cause of dental caries. The?
One. Oral diseases: suffering from dental caries, gingivitis, periodontitis, oral mucositis and dental caries, periodontal disease and other oral diseases, its mouth is easy to breed bacteria, especially anaerobic bacteria, which decompose to produce a sulfide, a taste of corruption, which produce bad breath.
Two. Gastrointestinal diseases, such as peptic ulcer, chronic gastritis, functional dyspepsia and so on, may be accompanied by halitosis. Recently, we also found that the incidence of halitosis in patients with Helicobacter pylori infection caused by many stomach diseases was significantly higher than that in the uninfected patients. The symptoms of halitosis were significantly alleviated after the eradication of Helicobacter pylori. The reason may be that Helicobacter pylori infection directly produces sulfides and causes halitosis.
Three. Smoking, drinking, drinking coffee, and often eat onions, garlic, leek and other spicy food, or appetite stinky tofu, stinky eggs and other smelly food people, but also prone to bad breath.
Four. Diet, weight loss, or can not eat because of illness, or the elderly salivary gland function decreased, women during menstruation endocrine disorder, resulting in decreased salivary secretion, anaerobic bacteria conducive to growth, so bad breath occurs.
Five. Girls halitosis: some women in puberty, ovarian dysfunction, lower levels of sex hormones, oral tissue resistance decreased, easy to infect bacteria, resulting in bad breath.

Bad breath can be caused by bad oral hygiene, periodontal disease, dry mouth, smoking, illness, or eating certain foods. When the poor oral hygiene and periodontal disease or lack of saliva, and bacteria build up, bad breath occurs, saliva to wash away food debris and bacteria has its necessity, some drugs, such as hypertension, psychotropic drugs or specific diseases may also cause dry mouth disease, occasional nasal or respiratory tract infections that can also cause bad breath, if bad breath persists, please check to see whether a dentist and dental related diseases.
In order to prevent dental caries bad breath, we should understand its etiology, described above is related to dental caries causes of bad breath, know the hope to be able to help with bad breath friends, then can we get rid of bad breath, restore confidence, able to communicate freely with others.

What are the causes of dental caries in children?

Early childhood caries is a common disease, we often hear parents say don't eat sweets, eat no teeth will be, however, many children are unable to resist the temptation of candy, many children appeared very early tooth, tooth is very painful, meaning worms eat what? Is the cause of dental caries among children?
The children eat too many sweets;
The lack of calcium
We do not pay attention to oral hygiene.
2, how about the symptoms of children's decayed teeth?
Dental caries is often caused by acid attack in the oral cavity, causing the tooth enamel to corrode, become soft, change color, and gradually develop into a cavity. Caries will not heal, such as non - treatment will continue to erode the dentin, pulp, leaving only residual roots.
Not only make the children feel the pain of dental caries and affect the appetite, chewing, digestion, absorption and growth, can sometimes lead to pulpitis, alveolar abscess, and even cause systemic disease affecting the health of children.
Toothache is a kind of pain is unbearable for adults, not to mention the child, and the child is a long body, caries will affect the normal diet of children, brought a lot of harm to children, so parents must remind the children develop good eating habits and health habits.

Why are tooth teeth more prone to dental caries?

Now, the incidence of dental caries is getting higher and higher, and some parents think it will improve when they grow permanent teeth. But during this time, the condition of the child will increase and cause other complications. So suggest parents, friends, when your child is suffering from the disease, must see the dentist in time. Here's a brief introduction to pediatric dental caries.
(1) deciduous teeth: the degree of calcification of deciduous teeth, enamel and dentin of deciduous teeth than permanent teeth enamel surface thin, low degree of mineralization, acid resistant ability, tooth acid susceptible to caries and caries development soon after. Some deciduous teeth that develop poorly and have decayed teeth have decayed when the teeth have not fully erupted. The development of the degree of calcification and teeth during pregnancy, and fetal postnatal nutrition has a direct relationship, so the teeth care should start during pregnancy, should strengthen the intake of protein, vitamins, inorganic salts and other nutrients, and balanced nutrition, to prevent the "congenital deficiency of deciduous teeth".
(2) the anatomical characteristics of deciduous teeth are: physiological physiology of the large gap, between the tooth and tooth surface contact is, these negative factors are likely to cause food residue retention, to create conditions for the accumulation of bacteria, which are prone to dental caries.
(3) children's bad eating habits: children often love to eat sweets and snacks, such as candy, biscuits, thick bread, cake and high sugar content of dairy products, the high sugar content, fine texture of the food in the mouth chewing soft, short time, less secretion of saliva, clean the surface of the teeth have less friction after eating the food residue, easy adhesion on the tooth surface, and the child is not easy to develop a regular and scientific method of brushing habits, thus creating conditions for the growth and reproduction of cariogenic bacteria.
(4) parents misunderstanding: many parents mistakenly believe that sooner or later the teeth will be instead of permanent teeth, so neglected to give children dental care for children is not correct, brushing attention, even allowed to take the wrong attitude, children's caries does not bring the child to the hospital for treatment in a timely manner. The children are in the growth stage, dental caries can affect local oral dental caries development system, not only caused serious pain, for further development of pulpitis and apical inflammation, but also because of reduced masticatory function, affect the digestive function, damage to health.
The above content is for you to introduce the content of children's dental caries, and hope to help your child's health. If you have any other questions, please consult with the experts concerned. Recommendation: as parents of children, we should educate and help children develop good oral hygiene habits.

What are the causes of dental caries?

At present, the theory of the etiology of dental caries is a four factor theory, which mainly includes bacteria, oral environment and host (that is, parasites, parasites, viruses and other parasitic organisms) and time. Its basic points are: cariogenic food sugars (especially sucrose and refined carbohydrates) attached tightly to the tooth surface and the acquired membranes formed by salivary proteins. This film not only can be firmly attached to the tooth surface, but also in the appropriate temperature, there is enough time for invasion of teeth in the plaque, the deep acid production, demineralization, and destruction of organic matter, produce caries.
1, bacteria
Is a necessary condition for the occurrence of dental caries, generally there are two kinds of cariogenic bacteria, is a genus of acid producing bacteria, mainly 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 be broken organic matter, after long-term effect can make the tooth formation of cavity.
2, oral environment
The oral cavity is the external environment of the teeth, which is closely related to the occurrence of dental caries, and the main ones are food and saliva.
(1) food is mainly carbohydrate, which is not only related to the formation of plaque matrix, but also the main energy source of bacteria in plaque. Bacteria can use carbohydrates (sucrose) and acid metabolism, synthesis of extracellular polysaccharide and intracellular polysaccharide, organic acid produced was beneficial to the production of acid and acid resistant bacteria, also conducive to demineralization of dental hard tissue; polysaccharide can promote bacterial adhesion on the surface of teeth and accumulation. And in the lack of exogenous sugar, provide a source of energy.
(2) saliva in normal conditions, saliva has the following functions: first, the role of mechanical cleaning; II antibacterial effect.
When the quantity and quality of saliva changes, the rate of caries can be affected. The incidence of caries in patients with xerostomia or saliva secretion is obviously increased. Patients with maxillofacial radiotherapy may have multiple caries due to the destruction of the salivary glands. On the other hand, when the amount of lactic acid in saliva increases, it also contributes to the occurrence of caries.
3 host
The teeth are the target organs in the process of tooth decay, and the morphology, degree of mineralization and histological structure of teeth are directly related to the occurrence of dental caries.
4, time
The occurrence of dental caries is a long process, from the beginning to the clinical caries formation of cavity usually takes 1.5 to 2 years, even if the cariogenic bacteria, suitable environment and susceptible hosts exist at the same time; dental caries will not happen immediately, only these three factors also exist for a long time, it may produce caries.
