A Cavity is a permanently damaged area in the hard surface of a tooth that develops into a hole. Cavities (also called Tooth Decay or Caries), are caused by a combination of factors, such as: the type of bacteria in your mouth, frequent snacking, sugary drinks, sugary sticky snacks, and not cleaning your teeth properly or often enough. Cavities must be filled and repaired by a Dentist, or they could result in serious damage to the tooth, oral infection, and tooth loss.
