Root canals are performed when the nerve tissue (pulp) of a tooth has been compromised, either from a cavity, crack or fracture of the tooth. The pulp contains the nerve, blood vessels, etc to keep the tooth alive and healthy. During this procedure the entire pulp of the tooth is removed and replaced with a filling material. Root canals are successful in about 90% of cases, and is a good option when we are trying to save a tooth.

Once a root canal has been completed, the tooth no longer has any blood supply. Because of this there is an increased risk of fracture of the tooth. Because of this a crown is usually recommended as a final restoration.
