Pain-Free Dentistry - The Wand
The discomfort of a dental shot is caused primarily by the pressure of the anesthetic. By controlling the pressure at which the anesthetic is delivered, a computerized injection system (called The Wand) greatly relieves this discomfort. Results are encouraging: 82 percent of the patients who experienced a computerized injection say it was absolutely painless.
Here's how it works. A very thin needle attached to a pen-sized wand is positioned near the gum, but before the needle actually touches the gum, a drop of anesthetic numbs the surface tissue.
As the dentist gently guides the needle into the gum, the tissue just ahead of the needle tip is numbed by the anesthesia. Once the needle is inserted, the computer slowly releases a stream of anesthetic. There's no sudden prick or burning sensation. And because the anesthetic can be targeted to just one tooth, the whole jaw doesn't have to be numbed.
This means that there is less lingering numbness; you can talk, eat and drink sooner after your dental appointment. While a computerized injection system is a relatively inexpensive instrument (about $1,000), it's also relatively new to dentistry.
