Pain Free Injections
The DentiPatch, a band-aid looking device, is applied by the dentist to the gums. Here lidocaine diffuses out of the patch and is delivered into the gum tissue. The DentiPatch can be used for most routine dental procedures. In cases where, delivery of anesthesia by a needle is neccessary, the DentiPatch can first be applied to prevent the pain of the subsequent needle injection.
A new needle anesthesia delivery system may also end painful dental visits. The pain patients experience from needle injections is caused not by the the needle itself but by the rate at which the anesthesia is injected into the gums.
The slower and more steady the dentist is when he or she injects the anesthesia the less painful the injection. Most dentists, however, can not inject the anesthesia slowly enough or at a steady enough rate to totally eliminate pain.
That is where the Magic Wand comes into play. This new device contains a microprocessor which monitors and controls the rate at which anesthesia enters the gum tissue making the injection virtually pain free. Most patients simply feel pressure rather than pain when the Magic Wand is used.
A new device may one day eliminate the need for anesthesia altogether. Electrical nerve stimulation works by stimulating the mouth with a small amount of electricity. The precise mechanism by which electrical anesthesia works is actually unknown. Some theorize that it may temporarily affect the pain nerves of the mouth so that they can no longer send pain impulses or that the stimulation may cause the release of the body' own pain killers.
With new technologies the pain and discomfort associated with dental visits may become a thing of the past. Now millions of people who fear going to the dentist may have a new reason to smile.
