Endodontic Retreatment Q & A

What indicates a root canal needs retreatment?

If pain recurs in a tooth that’s already had a root canal, or you experience swelling in the area, have the tooth examined immediately. Other symptoms of a problem include sensitivity to hot and cold temperatures and tooth discoloration.

What causes a root canal to fail?

Sometimes a root canal procedure wasn’t done properly or thoroughly, which can lead to a need for retreatment. In certain cases, a root canal is performed well but doesn’t heal properly due to issues such as:

  • Poor placement of the crown to protect the root canal
  • Complicated canal curves and anatomy that weren’t detected originally
  • Failure to place disinfectant in the canal before filling it with gutta-percha and sealing it

You may also develop a new problem that requires retreatment. If you fail to practice good oral hygiene or experience trauma, new decay may infiltrate the tooth and cause an infection.

Other problems that could cause you to need root canal retreatment include a tooth fracture or a cracked or loose crown that exposes the tooth to bacteria.

What happens during a root canal retreatment?

Dr. Vani makes a hole in the affected tooth and removes the filling material that was placed during your first treatment. She examines the tooth, looking for any canals that were missed and for signs of reinfection.

The retreatment involves thoroughly cleansing the internal canals of the tooth, disinfecting the area, shaping the canals, and placing new filling material. She seals the tooth with a temporary filling until a new crown is placed.

Why should I undergo root canal retreatment?

Retreatment can save a natural tooth, which is a preferred to losing the tooth and needing an implant, bridge, or dentures. Retreated teeth can still last a lifetime and preserve your natural bite feel and mouth structure.

Even if a root canal failed, newer technologies can make the new root canal more successful than the original one. If a repeat root canal isn’t an option, you may be a candidate for endodontic surgery.

If you have pain or other concerning symptoms at the site of a prior root canal, you may need retreatment. Call Dr. Vani or book an appointment online to have your tooth evaluated, so she can offer you the best possible treatment options.
