My dentist, Dr. Paul Kaplan, had looked into and purchased the Dentalvibe after I mentioned to him I had seen it highlighted on TV. It sounded like a great idea as getting the initial jab of anesthesia is always most unpleasant. I was pleasantly surprised that there was virtually no pain with the Dentalvibe. It certainly makes that part of a dental visit much more bearable. Kudos to the inventor of this device!!!
