What is the definition or description of: tooth decay?

Destruction: Tooth decay is the destructive process that occurs when the acids and bacteria in the mouth demineralize and dissolve away portions of the tooth structure. This can be stopped with proper tooth care and mineralization products (like fluoride) that your dentist can recommend.

Bacterial infection: The process of bacteria eating sugar over time leads to the breakdown of tooth structure called decay. This decay progresses if untreated and leads to nerve involvement and possibly tooth loss.

Tooth breakdown: Decay is the loss or breakdown of tooth structure. Very early stages, such as demineralization, can be reversed. However, once the tooth integrity is affected with a breakdown of the enamel and or dentin, then a filling is required to replace the lost tooth structure.

Cavity: Tooth decay is simply an infection in a tooth. Bacteria get in, party on, and cause collateral damage. Time to see your dentist (the sooner you catch it, the smaller it is, and the easier the solution).

Caries: Food for bacteria produces acids which attack the tooth enamel , dentin, and even root cementum, all the calcified parts of teeth. This leads to decalcification and hence decay. This can progress and destroy your tooth early removal w/ a filling beats neglect and afoot canal and/ or an extraction.

Bacteria and sugar: Decay is caused by bacteria which are naturally occurring in your mouth. When the bacteria are fed sugar, either simple like sweets or complex like bread or sugar, they produce acid which eats into the tooth.
