Root canal treatment is a dental procedure used to save a damaged or infected tooth. It involves removing the inflamed or infected pulp from inside the tooth, cleaning and disinfecting the root canals, then filling and sealing them to prevent reinfection. This treatment is typically needed when decay, cracks, or trauma allow bacteria to reach the pulp, causing pain or abscess. Performed under local anesthesia, it’s usually painless and helps preserve the natural tooth. A crown is often placed afterward to restore strength and function. Root canal therapy prevents tooth loss and maintains oral health
