Dental pulp, found in the center of each tooth, contains a nerve which extends from the tooth’s root to bring vital nutrients to the tooth. If a tooth’s pulp is injured, damaged, or infected, the nerve within the pulp will die and, unless endodontic treatment (root canal) is performed, the tooth may die as well. In many cases, root canal therapy (removal of the nerve tissue in the tooth) can save damaged teeth by preserving the tooth in the mouth.  After the root canal is successfully completed, restoring the tooth with a crown is usually highly recommended to preserve the tooth structure and provide strength for chewing.
