Charlestown Family Dentistry offers the use of a high pressured sand spray to prepare a tooth for a filling. Usually this procedure, referred to as air abrasion, can be completed without anesthetic. This is because no heat is generated when removing tooth decay, so the patient experiences little sensitivity. This state of the art technology allows the dentist to preserve more tooth structure. Since no anesthesia is required, the patient can have fillings completed in a painless manner, and not have to wait for the Novocain to subside before eating.
