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.
