Why do caries develop?

Keyes diagram

Bacteria and saliva intervene in caries production.

As has already been mentioned, a number of factors are involved in the formation of caries: foods, bacteria and constitutional factors characterizing each individual person.

All of us have bacteria in the mouth. These bacteria cause no problems, and some are even useful. However, when we eat too much sweet or sugar-containing food, the bacteria use it as a source of energy, decomposing it and releasing acids which in turn attack the enamel of the tooth.

These bacteria and the remains of food and sugar form so-called bacterial plaque, a film-like layer that covers the teeth and contains bacteria. This film facilitates the development of caries and diseases of the gums.
