Root canal treatment is a dental procedure used to save an infected or severely decayed tooth. The process involves accessing the tooth’s inner pulp, which contains nerves and blood vessels, cleaning out the infected or damaged tissue, and disinfecting the root canals. After thorough cleaning, the canals are filled with a biocompatible material to seal them and prevent reinfection. Finally, a dental crown may be placed on the treated tooth to restore its strength, functionality, and natural appearance, allowing patients to preserve their tooth and maintain their oral health.
