When retreatment isn't an option, an apicoectomy addresses infection from the root tip instead. Here's the full procedure explained simply.

What Is an Apicoectomy?

An apicoectomy is a minor surgical procedure that removes the very tip of a tooth's root, along with any surrounding infected tissue, and seals the end of the root from that point, addressing an infection that persists despite previous root canal treatment.

Why Would a Root Canal Fail in the First Place?

Complex or unusual canal anatomy that wasn't fully addressed during the original treatment, a new crack or fracture that developed after the initial procedure, or reinfection due to a compromised seal at the top of the tooth are among the reasons a previously treated tooth might develop a new or persistent infection.

Apicoectomy vs. Root Canal Retreatment

Retreatment involves reopening the tooth from the top, similar to the original root canal, to clean and reseal the canals again. An apicoectomy takes a different approach, accessing the infection from the root tip through the gum and bone rather than through the top of the tooth, which is generally considered when retreatment isn't possible or hasn't resolved the issue, such as when a crown or post makes reopening the tooth from above impractical.

The Apicoectomy Procedure

Under local anesthesia, a small incision is made in the gum near the affected tooth's root. The infected tissue at the root tip is removed, along with a small portion of the root end itself. The end of the root canal is then sealed from this direction, and the gum tissue is closed with stitches to heal.

How Long Does an Apicoectomy Take?

The procedure itself typically takes around thirty minutes to an hour, depending on the specific tooth and complexity of the case, generally performed as an outpatient procedure without requiring an overnight stay.

Recovery After an Apicoectomy

Some swelling, bruising, and mild discomfort in the days following surgery are normal, generally managed with prescribed or over-the-counter pain relief. Most people return to normal activities within a few days, with full healing of the surgical site taking a few weeks.

Does the Tooth Still Function Normally Afterward?

Yes, a successfully treated tooth following an apicoectomy generally continues to function normally for biting and chewing, since the procedure addresses the infection at the root tip without affecting the tooth's ability to sit in place and handle normal bite forces.

Success Rate of Apicoectomy

This procedure has a well-established track record in endodontic treatment, generally offering a good chance of resolving the underlying infection and saving the tooth, when performed on an appropriate candidate by a qualified provider, though individual outcomes depend on the specific case.

What If an Apicoectomy Doesn't Resolve the Infection?

In situations where an apicoectomy doesn't successfully address the problem, extraction of the tooth may ultimately become necessary, followed by a conversation about replacement options like an implant, bridge, or partial denture.

Who Performs Apicoectomies?

This procedure is typically performed by an endodontist, a specialist in root canal-related treatment, given the specific surgical technique and precision required.
