An apicoectomy is a treatment for a tooth which is infected or abscessed after it’s been root filled.
A form of endodontic surgery, apicoectomy is where infected tissue is removed and sealed. This treatment is usually only recommended if you have already had root canal therapy the tooth is reinfected or abscessed.
An apicoectomy is when the root is shortened to remove infected tissue and seal the end of the root within the bone. This is done by making an incision in the gum tissue to expose both the bone and the inflamed tissue. The inflamed tissue and the end of the root tip is then removed. Once the damage is removed a filling is placed to prevent infection and your gum tissue is sutured.
The healing time for this treatment can be a few months because the bone has to heal naturally around the root tip.
Generally speaking root canal therapy is all that is required to save a tooth from extraction. However, if the infection in the tooth continues it can create an abscess and an apicoectomy will remove the infection and restore health to the tooth.
