Our natural teeth are meant to last a lifetime, but sometimes damage or decay is so severe that the infection affects the network of blood vessels and nerves inside the tooth. If left untreated the infection can cause swelling and pain and eventually damage the surrounding jawbone. 

Endodontic therapy, also known as root canal treatment, offers an effective remedy for a badly damaged or infected tooth. During the procedure the inflamed or infected pulp is removed and the inside of the tooth is carefully cleaned and disinfected before being filled and sealed with a rubber-like material called gutta-percha. Afterwards, most teeth that have had root canal treatment should have a crown (cap) placed to help protect the tooth and restore it to full function.

Root canal treatment is most often performed when the nerve of the tooth is affected by decay or infection. It is also performed when a significant portion of the tooth is fractured or broken off. Teeth that have sustained moderate to severe trauma, even without breaking, often require root canal treatment. Root canal procedures may require one or more appointments to complete.

Root surgery (apicoectomy) is sometimes performed in addition to root canal treatment in order to help treat infections that are present at the tip of the root.
