The wand is the newest and most advanced way of administrating local anaesthetic.
What is it?
The Wand is essentially a computer-controlled dental injection. The flow rate of the local anaesthetic is controlled by a computer. This means that the injection is guaranteed to be slow and steady and therefore comfortable.
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.
What are the advantages?
- Researchers have found that the Wand induces less anxiety than any other injection method
- The precise control of flow rate and pressure reliably produces a comfortable injection even in potentially more "difficult" areas like the palate, where the tissue is less elastic
- The pen-like grasp of the wand allows the operator to rotate the hand piece, which can make it easier to glide the needle into the tissue
