The Wand is a revolutionary computer-controlled local anesthesia injection system that allows a more predictably comfortable injection, especially in the more sensitive areas of the mouth, such as the palate or front. It also allows the use of less anesthetic at certain times, and techniques can be used to eliminate the collateral numbing of your face, tongue, and lips. A microprocessor inside The Wand automatically compensates for different tissue densities, so the anesthetic is delivered at a constant pressure and volume that’s typically below the threshold of pain.
