How is tooth decay treated?

Tooth decay is treated by removing the decayed portion of the tooth and restoring it with a dental filling, crown, or other restorative material. If the decay has reached the pulp, the inner part of the tooth containing nerves and blood vessels, a root canal may be necessary to remove the infected tissue and save the tooth. In severe cases where the tooth is extensively damaged and cannot be saved, extraction may be required. Fluoride treatments can also be used to remineralize and repair early stages of decay.
