Endodontic Retreatment: Save Your Natural Tooth

Endodontic retreatment is performed when a previous root canal fails or new infection develops. The procedure removes remaining bacteria, cleans the canals again, and reseals the tooth to restore its health and function—helping you avoid extraction.

When is retreatment needed?

You may need retreatment if you experience:

Persistent or recurring tooth pain

Sensitivity when biting or chewing

Swelling or signs of infection

Darkening of the treated tooth

Failed Root Canal Treatment

Understanding Endodontic Retreatment

Endodontic retreatment is recommended when a previously treated tooth does not heal properly or becomes reinfected over time. Identifying the cause early and acting quickly can help preserve the tooth and prevent further complications.

Why Root Canal Treatment May Fail

In some cases, a tooth that has previously received root canal treatment may not heal properly or may become reinfected.

  • Delay in placing a crown or final restoration
  • Cracks or fractures allowing bacteria to reach the canals
  • Complex root canal anatomy not fully treated during the first procedure
  • New decay exposing the root canal filling
  • Contamination during the initial treatment

Symptoms That Indicate Retreatment May Be Needed

If you experience any unusual discomfort or changes in a previously treated tooth, it’s important to seek professional evaluation.

  • Pain when biting or applying pressure
  • Swelling around the tooth or gums
  • A pimple or abscess on the gum
  • In some cases, there may be no symptoms and the problem is detected only on an X-ray

How Endodontic Retreatment Is Performed

During retreatment, the endodontist reopens the tooth and removes the previous root canal filling materials. The canals are cleaned and disinfected again, and hidden canals or complex anatomy may be treated.

Once the canals are properly cleaned, they are sealed again and a temporary filling is placed until the final restoration is completed.
