Endodontic Retreatment Cases: A Comprehensive Review

Root canal retreatment cases are performed when a previously treated tooth continues to show pain, infection, swelling, or failure to heal properly. Common reasons for retreatment include missed canals, inadequate cleaning, leakage from a faulty restoration, or reinfection due to recurrent decay. During retreatment, the old filling material is removed, the canals are cleaned and disinfected again, and the tooth is sealed properly to improve long-term success. Early diagnosis and careful case selection are important for achieving a favorable outcome.
