Apicoectomy (Root-End Surgery): What to Expect and When You Need One
You had a root canal, and everything seemed fine. Then months or years later, the tooth starts acting up again: tenderness when you bite, a pimple on the gum, or an X-ray that shows a shadow at the tip of the root.
Before anyone mentions extraction, there's another option worth knowing about: an apicoectomy, also called root-end surgery or endodontic microsurgery.
What Is an Apicoectomy?
An apicoectomy is a small procedure that treats infection at the very tip of a tooth's root (the "apex") when a standard root canal or retreatment can't resolve it. Your endodontist accesses the root tip through the gum, removes the infected tissue and the last few millimeters of the root, and seals the end so bacteria can't get back in.
The goal is simple: keep your natural tooth.
When Is It Needed?
Most root canal problems are solved with the root canal itself, or with retreatment. An apicoectomy is usually considered when:
Retreatment isn't possible. A crown, post, or bridge would have to be destroyed to get back into the canals, or the canals are blocked or calcified.
Retreatment didn't work. Infection persists despite a well-done second root canal.
The anatomy is complicated. Tiny side canals or tight curves at the root tip can harbor bacteria that cleaning from the inside can't reach.
There's a persistent lesion. A healing problem shows up on imaging despite good treatment.
How the Procedure Works
Modern endodontic microsurgery looks very different from the surgery your parents may have had.
Numbing. The area is completely numbed. You'll feel pressure, not pain.
Access. A small opening in the gum gives access to the bone and root tip.
Removal. The infected tissue and the end of the root are removed.
Sealing. Using a surgical microscope and specialized materials, the root end is cleaned and sealed.
Closing. The gum is repositioned and closed with tiny sutures.
Most apicoectomies take about 30 to 90 minutes, depending on the tooth. The microscope is what makes the difference. It lets us see fine detail, work through smaller openings, and achieve better outcomes than older techniques.
Recovery
Most patients are surprised by how manageable recovery is.
Mild swelling and soreness for a few days are normal and are usually controlled with over-the-counter medication.
An ice pack on and off during the first day helps.
Stick to soft foods and avoid chewing on that side for a few days.
Keep the area clean, but be gentle while it heals.
Most people return to normal activity the next day.
Sutures are typically removed within a few days, and the bone heals over the following months. We'll follow up with imaging to confirm that healing is on track.
Success Rates and Why Imaging Matters
With modern microsurgical techniques, apicoectomies have high success rates, and a tooth that heals can last for many years. Careful diagnosis is what makes it work: we use 3D imaging to see the root tips, surrounding bone, and nearby structures before we ever start.
Is Saving the Tooth Worth It?
In many cases, yes. Your natural tooth is almost always better than a replacement. An implant or bridge can work well, but it costs more and involves more procedures, and it can't fully replace a healthy natural tooth. If there's a good chance to save it, it's worth hearing your options first.
Think You Might Need One?
If you've had a root canal and something still doesn't feel right, don't assume the tooth is a lost cause. An evaluation can tell you whether retreatment, an apicoectomy, or another approach is the best path.
