Root canal treatment for a multi-rooted tooth is an endodontic procedure used to treat infection or inflammation affecting teeth with more than one root, such as molars and some premolars. These teeth have complex canal systems that require precise diagnosis and treatment.

The procedure involves removing infected pulp tissue, thoroughly cleaning and disinfecting all root canals, and sealing them with biocompatible materials. This treatment relieves pain, prevents further infection, and allows the natural tooth to be preserved. Careful technique and modern endodontic tools ensure effective treatment, patient comfort, and long-term success.
