What is it?

The Wand is essentially a computer-controlled dental injection. The flow rate of the local anesthetic is controlled by a computer. This means that the injection is guaranteed to be slow and steady and therefore comfortable. Because a lot of people with needle phobia describe it as their “Magic Wand”!

Most people who have had a bad experience with injections think that needles sting because the skin is pierced, but this is usually not so! Most often, the sting was caused because the anesthetic was fired in too quickly. Obviously, it is possible for the dentist to control the speed with a standard syringe, but the idea of the Wand is to take out the “human error”. This can be very reassuring for people with previous bad experiences.
