Contrary to what most people believe, a root canal does not cause discomfort but is actually an effective treatment for relieving tooth pain. A common cause of tooth pain is infection of the interior tooth pulp. If not treated, this infection can spread to other teeth or even other parts of the body. Root canal treatment is the most effective way of cleansing the infection and relieving tooth pain. At Thomas Smile Designs we strive to make all your treatments anxiety-free so that you can live a lifestyle without pain.
