Endodontic surgery concerns itself with treating damaged root surfaces and the surrounding bone. Endodontic surgery may also be used for a diagnosis in cases where symptoms are present but problems fail to appear on the x-ray images.
If your tooth has calcification (calcium deposits which make the canal too narrow to perform a root canal), endodontic surgery may be necessary to clean and seal the remainder of the canal.
The most common endodontic surgery procedure is the apicoectomy. Apicoectomy is a procedure involving the surgical removal of a root end cavity and sealing of the root canal. The purpose of this procedure is to fight infection in the tissues surrounding the tip of the root, thereby saving the tooth from extraction.
