Dental caries (dental cavities) are ‘holes’ that occur in both milk and permanent teeth. They are caused acid produced when bacteria act on sugary foods on the teeth surface.
We can prevent dental caries by avoiding sugary diet and brushing our teeth regularly at least twice a day (morning and evening). Visiting a dentist twice a year helps in preventing cavities from forming and also by treating them early.
When cavities have already formed, different types of fillings are used to fill them depending on the age of the patient and the tooth surface affected.
Fillings are only possible for cavities that have not yet reached the pulp(life part) of the tooth.
