Cavities, also known as carries, are a common dental ailment caused by bacteria that create acid and eat away at your teeth. Cavities are often difficult to see with the naked eye, but left untreated, cavities can make their way to the nerve of a tooth and cause a toothache.

Cavities can only be diagnosed through an exam, and are usually treated by cavity fillings. Modern fillings are usually made to match your tooth color, and make the restoration almost invisible. A well cared for filling can last more than a decade.
