Sometimes, even after a successful Root Canal Treatment (RCT), a tooth may fail to heal completely or develop a new infection. In such cases, a Re-Root Canal Treatment (Endodontic Retreatment) becomes necessary to save the natural tooth and restore oral health.
At Dental 101, Kharadi, this advanced procedure is performed by Dr. Indrani Khadilkar – MDS in Conservative Dentistry & Endodontics (AIIMS, New Delhi), who is highly skilled in managing complex endodontic cases with precision and care.

What Is Re-Root Canal Treatment?
A Re-Root Canal is a dental procedure that involves reopening a previously treated tooth, removing old filling materials, disinfecting the canals, and sealing them again. This treatment is typically recommended when the original root canal has not healed properly or when new problems arise in the tooth.
Causes – Why a Root Canal May Fail
There are several reasons why an earlier root canal may require retreatment:
- Missed canals during the first treatment due to complex root anatomy
- Persistent infection that was not completely eliminated initially
- Leakage under fillings or crowns allowing bacteria to re-enter
- Fractured or broken restorations exposing the tooth to infection
- New decay that develops after the initial root canal
- Delayed crown placement, which leaves the tooth vulnerable
- Tooth injury or trauma after the first RCT
Symptoms That Indicate You May Need Re-Root Canal

- Swelling around the gums or jaw
