Apicoectomy
An apicoectomy is a surgical procedure that attempts to remove infection usually the result of a failed root canal surgery from the tip of the tooth root (apex) the are where nerves and blood vessels enter the tooth and travel through a canal inside the root and into the pulp chamber which is inside the crown or the part of the tooth visible in the mouth. During root-canal treatment the canals are cleaned and inflamed or infected nerve tissue is removed. Root-canal systems are very complicated with many small off-shooting branches. Sometimes even after root-canal treatment infected debris can remain in these branches and possibly prevent healing or cause re-infection later
