Allows practitioners the ability to deliver rapid onset of localized ‘‘single tooth’’ anesthesia without using a needle or conventional injection techniques. Utilizes a patented and innovatively designed tip that allows for an atraumatic PDL injection to be comfortable for the patient and prevents any damage to the ligaments or tooth cementum. Numbness for the patient is confined to a single tooth, eliminating the common discomfort for patients with numbness to their lips, gums, and cheeks.
