Treating a decayed tooth depends on the severity of the decay. The most common treatment for a decayed tooth is a filling, which involves removing the decay and replacing it with a filling material, such as amalgam or composite. If the decay is more extensive, such as reaching the pulp of the tooth, a root canal may be necessary in order to save the tooth. In this procedure, the decay is removed, and the pulp is replaced with a special filling material.
Other treatments may include crowns, which involve capping the entire tooth with a porcelain covering, or a dental implant, which replaces the tooth entirely. In some cases, if the decay is too severe, the tooth may need to be extracted.
The treatment for a decayed tooth should be determined by a dentist. The dentist will need to assess the degree of decay and make recommendations for the best course of action. It is important to address the decay as soon as possible, as it can spread to other teeth and cause further complications.
