Usually, a tooth that has undergone a root canal can last the rest of your life and never need further endodontic treatment. But if symptoms persist even after successful non-surgical endodontic treatment your endodntist may advise surgery to save your tooth. Sometimes calcium deposits make a canal too narrow for the instruments used in root canal treatment requiring a surgical procedure to treat an infection or inflammation in the bony area around the end of your tooth.Surgery will aid in diagnosis and treatment. Surgery allows your endodontist to examine the root of your tooth, find the problem, and provide treatment. Most common surgical procedure rendered is called Apicoectomy or Root end resection.
In this surgical procedure your endodontist reflects the gum tissue near the root end of the tooth ,examines the underlying bone, gains access to the root end ,removes infected tissue and resects the root end. He then seals the root end with an inert filling material and sutures the gum tissue back. Over a period of months the bone heals around the resected root end.
