If your tooth’s nerve chamber becomes infected by decay or damaged by trauma, root canal treatment is often the only way to save your tooth.
Inside the hard outer shell of each tooth is a specialized area called the pulp or nerve chamber. The pulp chamber contains a system of blood vessels, lymph vessels, and nerves, the pulp, which enters from the bone through the root canals. This system provides nourishment for the cells within the tooth.
Deep tooth decay or other injury can damage or infect the tooth pulp. In a root canal or endodontic treatment, the dentist removes the damaged or infected pulp and replaces it with a special filler that helps maintain the remaining tooth structure.
Some indications of the need for root canal treatment may be:
- Spontaneous pain or throbbing while biting.
- Sensitivity to hot and cold foods.
- Severe decay or an injury that creates an abscess (infection) in the bone.
PROCEDURE
 Step 1After the tooth is anesthetized, an opening is made through the crown and enters the pulp chamber. |
 Step 2The length of the root canals is determined. |
 Step 3Unhealthy pulp is removed. Canals are cleaned, enlarged, and shaped. |
 Step 4Canals are filled and sealed. A metal post may be added for structural support or to retain restorative materials. |
 Step 5The tooth is sealed with a temporary filling. Usually, a gold or porcelain crown adds further protection. |
