What is root canal treatment (endodontic therapy)?

Root canal treatment, also called endodontic therapy, is a dental procedure used to save a tooth that has become severely infected or damaged inside. The pulp, the soft tissue at the center of the tooth containing nerves and blood vessels, can become infected due to deep decay, repeated fillings, cracks, or trauma. When this happens, the infection causes pain and can eventually lead to an abscess if left untreated.

During the procedure, a dentist removes the infected or inflamed pulp from inside the tooth and then cleans and shapes the empty canal. The canal is then sealed with a rubber-like material to prevent bacteria from returning. Root canal treatment stops the infection and allows the patient to keep the natural tooth rather than have it extracted.

After root canal treatment, the tooth is often weakened because it no longer has a living pulp. For this reason, a tooth that has had endodontic therapy typically needs a crown to protect it and restore its strength and function. The crown covers and seals the treated tooth, allowing it to function normally for chewing. Finding a dentist experienced in both root canal treatment and crown placement ensures the best long-term outcome. You can locate qualified providers in your area to discuss whether root canal treatment is the right option for your tooth.
