Root canal therapy is used to save a tooth that has become infected. If a root canal is not performed on the tooth the infection will spread and cause the tooth to be lost.
A tooth becomes infected when the pulp, the soft tissue inside the tooth, become exposed to bacteria. The pulp is exposed when the outer, hard layer of the tooth is damaged through decay or injury.
Root canal therapy saves a tooth by removing the infected pulp and protecting the tooth from future infections.
In the root canal procedure, a small hole is drilled in the tooth and the pulp is surgically removed. Then we clean the inside of the tooth and seal it off to prevent future infection.
The root canal procedure itself is done under a local anesthetic so it is painless. You may experience soreness in the area after your treatment.
