Introducd:What are dental caries?

Dental caries, often called cavities, are erosions of the surface of the tooth caused by the combined effects of bacteria, acids, plaque and tartar. Dental caries are common in both children and adults, and they occur most often as a result of poor dental hygiene. Dental caries are usually painless at first, but they may become painful if they spread to the nerve or root of a tooth. Left untreated, dental caries can progress to a tooth abscess, which is a more painful and potentially serious condition. 

Dental caries are common, but they can often be prevented by practicing good dental hygiene, including regular brushing and flossing. Dental caries usually do not require emergency medical care unless they become painful, do not respond to over-the-counter pain relievers, or progress to a tooth abscess. Treatment includes removing the decayed material with a drill and filling in the resulting hole with a stable dental material.

Seek prompt medical care if you suspect you have dental caries, if you have a toothache lasting more than a few days, or if your tooth pain cannot be controlled by over-the-counter pain relievers.
