necessary when undergoing dental procedures. The intensity of the electric stimulation increases when the mouth is open because the outer skin is then stretched more tightly over the soft inner tissues where the numbness is required.
The control unit fits comfortably in the palm of the hand. The patient simply increases the level of electrical stimulation by rotating the amplitude knob. An amplitude reading of between 10 and 15 is the average for most patients, said Harre. At that point patients report a steady electrical sensation but no pain. They are usually ready to begin treatment within two or three minutes after stimulation begins.
Patient Esther Guimond tried electronic anesthesia at Dr. Harre’s office for deep periodontal cleanings because she hates the lingering numbness of local anesthesia. She was amazed at how well the system worked.
“1 was kind of nervous at first, but after 10 minutes, when nothing was happening, I laid back and relaxed. 1 could feel some pressure, because there was a lot of scraping, but 1 had no pain.”
She received electronic stimulation steadily for about an hour, experiencing only mild tingling and occasional muscle spasms around her mouth and eye. When the cleaning was over, she turned olT the control unit and felt no after-effects. Best of all, there was no numbness.
Mrs. Guimond has since used electronic anesthesia four or five times, once for a tooth filling. “You don’t get numb but there is no pain. If 1 could get up from there without a couple of hours of numbness, that’s great,” she said.
