A root canal treatment is a dental procedure that involves the removal of infected soft tissue (dental pulp) inside a tooth. It's also known as endodontic treatment.
You may need more than one visit to your dentist or dental specialist (endodontist) for this treatment.
Root canal treatment can save a tooth that would otherwise need to be extracted.
A tooth can have up to four roots containing blood vessels and nerves. During a root canal treatment, damaged or infected dental pulp is removed, and the inside of the tooth is cleaned, disinfected, filled, and sealed. If needed, a filling or crown is placed to restore the chewing surface.
Root canal treatment is performed to save a tooth affected by decay, cracks, injury, or wear and tear—common causes of severe toothache, pus around the tooth, prolonged sensitivity to hot or cold, or tooth discoloration.
Depending on the case, the cleaning process may take one or more appointments, followed by a filling or crown in subsequent visits. Preserving your natural tooth through a root canal helps maintain function and prevents the need for further tooth replacement treatments.
