Retreatment of multi-root endodontic treatment
Revision of a previous root canal on a multi-root tooth.
Retreatment of a previous root canal on a multi-root tooth revisits a complex case where the initial therapy did not fully resolve infection or new problems have developed. Molars and multi-rooted premolars require meticulous re-instrumentation of each canal.
Failed root canal treatment on back teeth is not uncommon due to intricate canal anatomy, calcifications, or structural challenges. Retreatment can still save the tooth when the roots and surrounding bone remain in acceptable condition.
What to expect
Advanced imaging guides the procedure. Old filling material is removed from all canals, which are disinfected, shaped, and refilled. Because of the complexity, treatment may take longer than single-root retreatment and could span multiple visits.
Who is it for
Multi-root retreatment is considered when the tooth has sufficient remaining structure and accessible canals. Your dentist will discuss success rates, risks, and whether saving the tooth through retreatment is preferable to extraction and replacement.
After your treatment
A crown is strongly recommended after retreatment on molars to prevent splitting. Maintain regular check-ups and report any recurring pain or swelling without delay.
