The relationship between food and dental caries are as follows

First, nutrients in food may enhance the anti-dental caries force. In the growth and development of teeth, such as proteins, as well as calcium, phosphorus, iron, and other trace elements of the lack of dental hypoplasia can increase the incidence of dental caries.

Second, high-fat foods can significantly reduce oral bacteria and reduce the incidence of dental caries.

Third, the food can be a product of metabolism of oral bacteria - the acid corrosion, caused by dental caries. High sugar content of food than the low-sugar content of food more easily lead to tooth decay. Viscous and sweet, such as bread, cake, toffee, and so most likely to increase in the incidence of dental caries. Sugar drink, do not increase in dental caries. As a result, do not let small children often develop the habit of eating sweets, in particular sugar on the teeth before bed against the largest.

Fourth, fibrous food such as vegetables, meat, and so on teeth cleaning and mechanical friction, and it is not easy fermentation, to some extent to reduce the incidence of dental caries.
