When the nerve, or innermost part of the tooth, either dies or abcesses, a root canal may be needed to save the tooth. You may sometimes have sensitivity, pain to temperature, biting, or a spontaneous pain that needs no stimulus. If the root is healthy, a root canal is a great option to allow you to keep the tooth. A very delicate procedure is done using small files, irrigating and sterilizing solutions, and a final sealer in the root to remove the nerve and then seal this area from further infection. On occasion, we may refer our patients to an endodontic specialist to manage more involved or complicated cases.
