Sometimes the infection persists even after root canal therapy. In these cases, an apicoectomy, or root end resection can be performed to remove diseased tissue.
- An incision is made to allow access to the base of the tooth. The inflamed or infected pulp is treated and the canals are carefully cleaned and shaped.
- A small filling may be placed in the remaining tip of the tooth to seal the root canal. The gum tissue is stitched back into place.
- A crown is placed to protect the tooth.
