Root canal treatment, also known as endodontic treatment, is a dental procedure performed to treat and save a tooth whose pulp tissue has become inflamed or infected due to various reasons (e.g., decay, trauma). During this treatment, the infected or inflamed pulp tissue is removed from inside the tooth, the root canals are cleaned and shaped, and then filled with biocompatible filling materials. The primary goal of the treatment is to eliminate infection, alleviate pain, prevent tooth extraction, and preserve the tooth's natural function within the jawbone.
