Root Canal Treatment
This procedure removes dental pulp when it has become dead or infected. Dental pulp is the soft core of the tooth. It contains nerves, blood vessels, and connective tissue. The pulp extends from the top of the tooth, called the crown, all the way down to the roots, in branches called canals.

Dental pulp may become infected because of:
When dental pulp becomes infected or dies, a painful abscess within the jawbone will occur. Removing dead or diseased dental pulp will prevent infection from spreading to other areas of the mouth and destroying bone around the tooth. If a root canal is not done, the tooth will need to be removed.
Common signs of pulp problems include:
- Pain when biting down on a tooth
- Pain when the tooth is not being used
- Sensitivity to hot or cold food or beverages
- Tooth discoloration
- Swollen gums around the infected tooth
- A draining boil-like structure (called a fistula) on the gum adjacent to the tooth
