Root canal therapy, also known as endodontics, is used when the nerve supply to a tooth has been damaged or decayed to the point that it can not be saved. It is an important treatment used to prevent and help resolve a dental infection and save a natural tooth from extraction. This procedure is performed when there is enough sound root and crown structure remaining to eventually restore form and function to the tooth.
There is a single central chamber or multiple ones inside every tooth. The chambers contain connective tissue, a nerve supply, and blood vessels. The core tissues, or dental pulp, help your tooth grow and mature before they emerge in your mouth. When the dental pulp is irreversibly damaged or has died, a root canal is required.
During root canal therapy, the chamber of the tooth is cleaned and shaped and then filled with a special inert material. The tooth is then sealed to prevent any subsequent infection. Once the procedure is complete, the tooth should be fully restored.
