What is an Apicoectomy?

An Apicoectomy, or Root-End Resection, is the removal of the root tip and the surrounding infected tissue of an abscessed tooth. This procedure may be necessary when inflammation and infection persists in the area around the root tip after root canal therapy or root canal retreatment.

Step one:

After the tooth is "numbed", the
gum is reflected (lifted) to uncover the underlying bone and the
root end of the tooth. The root-end is resected (removed) with all
the surrounding infected tissue.

Step two:

Step three:

After a few months, the bone around the root-end has healed, and all symptoms are gone.
