Root canal retreatment may be necessary for a number of different reasons, and symptoms may or may not be present with these cases. If you experience pain or swelling with a tooth that has had root canal treatment, you should consider scheduling a consultation.
Dr. Daugherty, evaluates the problem using high-end technology, such as an in-office digital X-ray, and microscopes.
Initial root canal treatments have a high success rate; however, retreatment may be necessary if a problem develops. In fact, root canal retreatments have an excellent success rate once the problem is corrected.
Why do I need root canal retreatment?
There are many reasons why your initial root canal treatment may have failed, even if the complications come long after the treatment. Your initial root canal treatment might heal improperly because of:
- Narrow or convoluted canals inside the tooth
- New decay to the tooth
- A cracked crown
- Poor crown placement
- Saliva entering the canals of the tooth
- Missed canals
- Under cleaned canals
Root canal retreatment gives you a second chance at keeping your natural tooth. You should report new pain or tooth sensitivity as soon as you notice it.
What happens during root canal retreatment?
Root canal retreatment is similar to the original root canal treatment. Initially, Dr. Daugherty numbs the area around the tooth, so you are comfortable while the treatment is done. The old root canal material is removed, problem areas are identified, and disinfection of the interior of the tooth is done.
Dr. Daugherty may use X-ray imaging to confirm that no extra material within the canals needs to be cleared. Then, he refills the tooth with a rubber material called gutta-percha. This material seals the tooth so bacteria can’t enter the canals within.
Finally, Dr. Daugherty places a temporary filling on the tooth to protect it and refers you back to your general dentist.
