An apicoectomy is a surgical endodontic procedure used to treat infection that remains around the tip of a tooth root after root canal treatment. During this procedure, the dentist or endodontist removes the apex, which is the very end of the tooth root, along with any infected or inflamed tissue surrounding it.
After the root tip is removed, the end of the root canal is cleaned and sealed with a special filling material to help prevent further infection. Apicoectomy is typically considered when a conventional root canal or retreatment has not fully resolved an infection. The goal of the procedure is to preserve the natural tooth while eliminating the source of infection in the surrounding bone.
