Definitions for "Dental caries"
Keywords:  caries, dentin, enamel, decay, tooth
decay of the teeth.
Decay of teeth due to penetration of bacteria through the enamel to the dentine.
A local disease of the teeth (caries is derived from the Greek word for "rottenness") that involves the action of specific bacteria in the mouth and the presence of certain substrates (such as sugar) required for bacterial action. Fluorine appears to prevent decay by rendering the structure of tooth enamel more resistant to acid-producing bacteria.
