Root canal retreatment for three root canals is an advanced endodontic procedure performed when a previously treated multi-canal tooth develops recurrent infection or ongoing symptoms. The procedure involves removing the existing filling material from all three canals, followed by thorough cleaning, disinfection, and precise refilling.

This treatment addresses residual bacteria, complex root canal anatomy, or leakage that may have caused failure of the initial therapy. By effectively sealing all canals, retreatment helps eliminate infection, relieve discomfort, and preserve the natural tooth. The procedure is carefully planned to ensure long-term success, proper healing, and patient comfort.
