Cavities Directory
Cavities are caused when the teeth begin to decay due to food being left on the teeth. The bacteria in your mouth produce acid and become plaque, which eats away at the teeth. A dentist can tell if you have a cavity if the tooth is soft when touched by a dental instrument. Treatments include fillings for common cavities and crowns for advanced tooth decay. Follow the links below to find WebMD's comprehensive coverage about how a cavity is caused, what it looks like, how to treat it, and much more.
