Surgical Retreatment Therapy
There are several surgical procedures, which are used to retreat root canal-treated teeth that have developed problems. The most common procedure is an apicoectomy. It addresses a persistent infection by first lifting the gum tissue, which is covering the tooth, to expose the underlying bone. The infected tissue, along with part of the root, is then removed. The apex of the remaining canal system is cleaned and a bio-compatible filling is placed to seal the remaining canal system from the bone. This procedure helps save the tooth and restore its functionality.
