The Wand is a revolutionary new computer controlled local anesthesia injection system that can provide a more comfortable and effective anesthetic delivery. Whether you get nervous about the injection or not, The Wand allows a more predicably comfortable injection, especially in the more sensitive areas such as the palate or front of the mouth. It also allows the use of less anesthetic and at certain times, techniques can be used to eliminate the collateral numbing of your face, tongue and lips. The needle is not what causes the main discomfort of an injection. It is the pressure and volume of the fluid going into the tissues. The microprocessor inside The Wand automatically compensates for different tissue densities. The anesthetic is delivered at a constant pressure and volume that's typically below the threshold of pain. The computer also provides a flow of anesthetic directly ahead of the needle. This numbs the site of insertion and develops a "pathway of anesthesia" so you hardly feel the needle at all. The Wand delivers the anesthetic at an optimal flow rate for a confortable injection every time.
