What Is Apical Resection? What to Do When Root Canal Treatment Is Not Enough?

Root canal treatment is one of the most commonly performed methods to save infected teeth. However, in some cases, this treatment may not be sufficient.

At this point, the solution is apical resection (root-end surgery).

What Is Apical Resection?

Apical resection is a surgical procedure in which the infected tissue at the tip of the tooth root is removed.

During this procedure:

  1. A small portion of the root tip is cut
  2. The infection is completely cleaned
  3. The area is sealed with a special filling

The goal is to preserve the tooth in the mouth without extraction.

When Is Apical Resection Necessary?

It is preferred in the following situations:

  1. Failure of root canal treatment
  2. Recurrence of infection
  3. Formation of cysts or lesions at the root tip
  4. When root canal treatment cannot be performed due to anatomical limitations

How Is Apical Resection Performed?

The procedure is usually completed in a short time and is quite comfortable.

Treatment Steps:

  1. Local anesthesia is applied
  2. The gum tissue is opened
  3. The infected root tip is removed
  4. The area is cleaned and sealed

The patient does not feel pain during the procedure.

Recovery Process and Aftercare

Recovery after apical resection is generally quick:

  1. Mild pain may occur during the first few days
  2. Swelling subsides in a short time
  3. Return to normal daily life within 3–7 days

Advantages of Apical Resection

  1. Preserves the natural tooth without extraction
  2. Maintains aesthetic and functional integrity
  3. Helps avoid more invasive procedures
  4. Provides a long-term solution

Conclusion: Is It Possible to Save the Tooth Instead of Extracting It?

Yes. Thanks to apical resection, a tooth can be saved even after a failed root canal treatment.

When applied in the right cases, this method is an effective treatment option that extends the lifespan of the tooth.
