Emmi-dent Oral Waver Ultrasound Electric Toothbrush cleans like no other electronic toothbrush on the market. It uses real 100% ultrasound waves that create over of 90 million ultrasonic impulses per minute. Unlike regular sonic electric toothbrushes that clean via abrasive brushing, Emmi-dent gives your teeth and gums the deepest clean with ultrasound technology, without brushing and, therefore without the risk of hurting the tooth enamel and sensitive gums. To clean, simply hold the Emmi-dent electric toothbrush head over each section of your teeth (don’t brush!). A timer will alert you to move on to the next section after 6 seconds. Our patented ultrasound wave technology can reach deep inside hidden areas where ordinary toothbrushes cannot reach. The Ultrasound even cleans inside tiniest crevices, and micro gaps to remove harmful plaque, penetrate gum tissue, and increase blood circulation. Multiple clinical studies conducted by Ormed University of Witten/Herdecke have shown that Emmi-dent reliably removes harmful plaque and build-up that can cause cavities, gingivitis, and periodontitis. Use the Emmi-dent ultrasound technology for most gentle deep-cleaning completely without abrasive tooth-brushing.
