In most cases, once your tooth has undergone root canal therapy it will not require further endodontic treatment for the rest of your life. In certain situations, however, the tooth may not heal properly, may become inflamed, or may develop a new infection. When this occurs, Drs. Richard J. Pasiewicz or Ryan Teahen may recommend endodontic surgery called an apicoectomy. This treatment can help prevent an extraction and restore the health and strength of your tooth.
