Root Canal Therapy

 

Root canal treatment or endodontic therapy is necessary for a variety of reasons. Sometimes deep cavities, large fillings, fractured teeth or trauma to a tooth may cause the nerve to be damaged. Once the nerve is damaged, the pulp tissue inside the tooth becomes infected. By the time the pulp is infected it must be treated, and cannot heal on its own. Symptoms that the pulp has become infected may include sensitivity to hot/cold or sweets, pain, swelling, pain to biting or pressure, and a bad taste in the mouth. Sometimes, however, no symptoms are apparent from a nerve that has died inside a tooth, and the person is unaware of any problem until a checkup.

A root canal is performed by numbing a tooth and cleaning out the infected pulp tissue. The inside of the tooth is disinfected and a filling material is placed in the canals of the tooth. Following root canal treatment most teeth will require a crown to provide adequate strength and function in the tooth again.
