A root canal treats a dental condition known as pulpitis or irreversible pulpitis. Due to extensive decay, trauma, or recurrent dental treatments, the fragile pulp of a tooth can become inflamed or infected, known as pulpitis. This condition can cause intense pain, sensitivity to hot and cold temperatures, swelling, and even the formation of an abscess. This procedure is performed to alleviate these symptoms and save the tooth. The damaged or infected pulp is removed during the treatment, and the tooth’s interior is cleaned, sanitized, and then sealed to stop the spread of infection. This treatment helps relieve pain, restore oral health, and preserve the natural tooth structure.
