If you had a severely damaged or infected tooth, your dentist recommended you visit an endodontist in Huntsville to save it from extraction using root canal therapy. This is among the most commonly performed restorative treatments because it is safe and effective for reinstating the health of a compromised tooth. Although they now have over a 95% success rate, there are times when a root canal can fail. Do not worry. You do not need to have your tooth removed. Instead, it can be saved with an apicoectomy.
