Posted at 08:02h in Root CanalA root canal is a treatment that targets infected teeth. Sometimes, despite a thorough dental care routine, our teeth may become sensitive or infected. A root canal is necessary when the pulp of the tooth, which contains the nerves, becomes infected, inflamed, or irritated due to tooth decay. This can cause a lot of pain, and the infection can spread to other teeth and other areas of the body through the bloodstream. A Ravenswood area dentist will attempt to discover the source of the pain and determine if a root canal is necessary.
