The teeth are held firmly in place by strong roots that extend into the jawbone. Molars and premolars tend to have several roots, whereas the front incisors only have a single root. The end or tip of each root is termed the apex. The apex is where the nerves and blood vessels enter the tooth, and aids in the delivery of blood to the crown (the part of the tooth you can see in your mouth).

A root canal treatment refers to the cleaning of the nerve canals and the removal of infected and inflamed tissue within the root. When the inflammation or infection persists after the root canal treatment, an apicoectomy may be required. An apicoectomy is essentially the removal of the apex (or root tip), followed by a filling procedure to seal the root from further infection. When left untreated, infected roots can damage other teeth, spread infection, and cause resorption of the jawbone.

Reasons for an apicoectomy

Infected and inflamed soft tissue around the root of a tooth can be exceptionally painful and debilitating to the patient. The purpose of an apicoectomy is to eliminate the infection in the tissue and to ultimately preserve the function of the tooth and save it from extraction. An apicoectomy will rarely be considered as a viable treatment option unless a prior root canal treatment has failed.

There are several reasons why an apicoectomy may be necessary:

• Small Adjoining Root Branches – Roots are extremely complex and can contain many tiny branches. If these tiny branches cannot be cleaned and sealed when the root canal treatment is performed, inflammation can persist.
• Blocked Root Canal – In some cases, the dentist is unable to effectively clean a root canal because it is blocked by a fractured file left behind from prior root canal treatment. Infection and debris can quickly affect adjacent teeth.
• Narrow or Curved Root Canals – When the root canal is poorly shaped, the endodontic files cannot reach the root tip. Continuing infection or re-infection can then occur.

What does getting an apicoectomy involve?

An apicoectomy is best performed by an endodontist (root canal specialist) due to their level of training and use of high powered microscopes allowing for a successful treatment outcome. Prior to the surgery, an antibiotic or anti-inflammatory medication may be prescribed to treat the underlying infection. X-rays will then be taken to enable the endodontist to plan the apicoectomy, which will be performed under local anesthesia.

A small incision is made in the gum to expose the underlying tooth root and apex. In some cases, a tiny fraction of the jawbone may need to be removed in order to properly expose the root. The edge of the root tip and any infected connective tissue will be removed using ultrasonic instruments. The root will be sealed using a retrofill (filling material) and the wound will be closed using sutures.

Post-surgery care instructions and pain medications will be provided as needed. The connective tissues will fully heal within a few months after the procedure.

If you are experiencing any signs or symptoms, such as pain or swelling associated with a tooth that has had a root canal, we encourage you to contact our office immediately to schedule an appointment.
