After each patient’s visit we disinfect the examination room and strictly adhere to guidelines set by the American Dental Association (ADA), the Occupational Safety and Health Administration (OSHA), and the Center for Disease Control (CDC). The water that Carolina Dental Associates uses is disinfected with ultraviolet technology in order to provide you with clean, pure water.
