Dr. Sunderland uses a computer controlled anesthetic delivery system that provides immediate pain free dental anesthesia for all injection types. Instead of one large, stinging injection, a computer-controlled flow of anesthesia is delivered. This technology is revolutionizing dental anesthesia by taking away the pain, anxiety, and stress associated with conventional syringes.  The benefits of STA Single Tooth Anesthesia is less trauma to the surrounding tissues, more efficient flow of anesthetic solution through tissues resulting in a more rapid onset an longer duration anesthesia. Less stress to the patient means less stress to your dental team!
