Root canal treatment is a dental procedure used to treat infection or damage inside a tooth. The inner part of the tooth, called the pulp, contains nerves, blood vessels, and connective tissue. When the pulp becomes infected due to deep decay, cracks, or injury, it can cause severe pain and lead to serious dental complications if left untreated. Root canal treatment helps save the natural tooth by removing the infected tissue.

During the procedure, the dentist carefully removes the infected or damaged pulp from the tooth. The inside of the tooth is then cleaned, disinfected, and shaped to eliminate bacteria and prevent further infection. After cleaning, the empty canals are filled with a special material that seals the space and protects the tooth from future problems.
