Root Canal Revision
A retreatment procedure that corrects a previously performed root canal that has failed or become reinfected.
A retreatment procedure in which a previously completed root canal is reopened, the canals are re-cleaned and reshaped, and the tooth is resealed to address a failed or reinfected root canal treatment.
The existing crown or filling is removed to access the canals, old filling material is carefully taken out, the canals are re-cleaned, reshaped, and disinfected, then refilled and sealed with a new restoration placed on top.
Saves a tooth that would otherwise be lost to persistent infection, eliminates recurring pain, and gives the original root canal treatment a second chance to succeed.
Frequently Asked Questions
Common questions about root canal revision.
Patients whose previous root canal has failed, resulting in recurring pain, persistent infection, or a new abscess that indicates the tooth needs to be retreated to be saved.
The tooth is numbed and the existing filling material is carefully removed before the canals are re-cleaned and resealed. Discomfort following the appointment is typically mild and short-lived.
The procedure typically requires two appointments spaced one to two weeks apart — one to remove the old filling material and re-clean the canals, and a second to place the final restoration.
The retreated tooth will still need a crown to protect it long term. The tooth should be monitored at follow-up visits to confirm healing is progressing as expected.
Some soreness around the treated tooth is normal for a day or two. Avoid chewing on that side until the permanent crown is placed.
