Root canal treatment for a single-rooted tooth is an endodontic procedure performed to treat infection or inflammation of the dental pulp in teeth with one root, such as incisors, canines, and some premolars.

The procedure involves removing the infected pulp, thoroughly cleaning and disinfecting the root canal, and sealing it with biocompatible materials. This treatment relieves pain, prevents reinfection, and allows the natural tooth to be preserved. Modern endodontic techniques ensure precision, patient comfort, and long-term functional success.
