Root canal treatment is a common dental procedure used to save a tooth that has become infected or severely damaged due to deep decay, cracks, or trauma. During the procedure, the dentist removes the infected pulp tissue from inside the tooth, carefully cleans and disinfects the root canals, and seals them with a special filling material to prevent further infection. Local anesthesia is used to ensure the treatment is comfortable and virtually painless. In many cases, a dental crown is placed after the procedure to restore the tooth’s strength and function. Root canal therapy helps relieve pain, preserves the natural tooth, and improves overall oral health, allowing patients to chew and smile confidently again.
