Root Canal Surgery
Surgery may be needed when conventional root canal treatment cannot be performed
or has not been successful. Root canal surgery can:
- Check the end of the root of a tooth for cracks
- Remove parts of a root that could not be sealed during conventional root canal treatment
- Clear up an infection that has not healed after conventional root canal treatment.
The most common root canal surgery is an apicoectomy. An apicoectomy involves:
- Drilling a hole in the enamel of the tooth to access the root canal and pulp
- Removing the pulp
- Filling the root with a substance called gutta-percha, which is a natural latex
- Cutting the gum tissue near the tooth to remove infected or inflamed tissue and removing the root end
- Stitching the incision
Root canal surgery known as endodontic microsurgery may also be required
to preserve a tooth. This type of surgery depends on the nature of the problem
prior to treatment and the response of the tissues after initial therapy.
