Cavities

[Couch Potatoe]

Cavities are decayed areas in the teeth, the result of a process that gradually dissolves a tooth’s hard outer surface (enamel) and progresses toward the interior.
(See also Overview of Tooth Disorders.)

Bacteria and debris build up on tooth surfaces, and the bacteria produce acids that cause decay.
Tooth pain occurs after decay reaches the inside of the tooth.
Dentists can detect cavities by examining the teeth and taking x-rays periodically.
Good oral hygiene and regular dental care plus a healthy diet can help prevent cavities.
Fluoride treatments can help cavities in the enamel heal, but for deeper cavities, dentists must drill out the decay and fill the resulting space.

Along with the common cold and gum disease, cavities (which are caused by bacteria) are among the most common human afflictions. If cavities are not properly treated by a dentist, they continue to enlarge. Ultimately, an untreated cavity can lead to tooth loss.
