Root canal retreatment for two root canals is an endodontic procedure performed when a previously treated tooth continues to show signs of infection or discomfort. The treatment involves removing the old filling material from both canals, followed by thorough cleaning, disinfection, and precise refilling with biocompatible materials.

This procedure addresses residual bacteria, complex canal anatomy, or leakage that may have caused treatment failure. By properly sealing both canals, retreatment helps eliminate infection, relieve symptoms, and preserve the natural tooth. The approach is carefully planned to ensure effective healing, long-term stability, and patient comfort.
