Root Canal Therapy

A root canal helps you to save a tooth if its nerves become infected. Preserving the tooth helps to prevent nearby teeth from shifting and causing bite problems. In addition, you avoid the uncomfortable process of having to extract the tooth.

Root canal therapy, or endodontic treatment, removes the infected or dying dental pulp from inside the tooth. Underneath the protective outer enamel is the root canal system which is made up of the dental pulp and nerve endings that keep the tooth healthy during development. However, once the tooth has fully developed, it can survive without the dental pulp.

Whenever a tooth has deep decay or damage, it can become abscessed, which occurs when the dental pulp becomes infected. An infected dental pulp can cause numerous problems such as pain, swelling, further infection and other serious oral problems. As a result, the infected pulp has to be removed to save the tooth.

During your root canal, you will first be given a local anesthesia to freeze the tooth. A rubber dam is placed around the tooth to prevent bacteria from entering the tooth during the procedure. A small incision is made to allow access to the damaged dental pulp. The dentist uses special tools to carefully remove the pulp and clean the root canal system. The canal is refilled and resealed before a crown is cemented to the to protect it.

It takes 1 to 2 appointments to perform a root canal. Following your procedure, your tooth might be tender so be careful with chewing and brushing. Although some tenderness is expected, severe pain is not common, so be sure to contact your dentist right away if you experience any pain.
