What is the cause of dental caries formation?

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

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