Root Canal Therapy is a dental procedure used to treat infection or damage within the pulp—the innermost soft tissue of the tooth that contains nerves and blood vessels. When a tooth is severely decayed, cracked, or traumatized, bacteria can enter the pulp, leading to pain, swelling, or even abscess formation. During the procedure, the dentist carefully removes the infected or dead pulp tissue, cleans and disinfects the root canals, and then fills and seals them with a biocompatible material to prevent further infection. The treated tooth is usually restored with a crown to protect it and restore full function. Root canal therapy is a highly effective way to save a natural tooth, eliminate pain, and maintain your smile without the need for extraction or replacement. With modern techniques and anesthesia, the procedure is generally painless and helps preserve your natural bite and chewing ability.
