A root canal is a dental procedure that involves removing the damaged or infected pulp (soft tissue) from the inside of a tooth. The pulp is located in the center of the tooth and contains nerves, blood vessels, and connective tissue.
When the pulp becomes infected or inflamed due to decay, trauma, or other reasons, it can cause pain, sensitivity, and swelling. A root canal is done to remove the infected or damaged pulp and to prevent the spread of infection to other teeth or parts of the body.
During a root canal procedure, the dentist will make a small hole in the top of the affected tooth and remove the pulp using special tools. The tooth is then cleaned and filled with a rubber-like material to seal it off from further infection.
After a root canal, the tooth may be covered with a crown or filling to restore its shape and function. With proper care, a tooth that has had a root canal can last a lifetime
