Emmi-dent generates upto 96 Million Oscillations per minute / Patented ultrasonic microchip which is located inside the brush head. Emmi-dent is the no-brushing toothbrush innovation that uses 100% ultrasound to clean your teeth and gums. Ultrasound effectively removes everyday stains (coffee, tea, nicotine and wine) and kills bacteria leaving your teeth sparkling clean. In comparison to all other toothbrushes Emmi-dent ultrasound destroys bacteria and germs in even the most difficult to reach areas (e.g. up to 12mm below the gum line because the ultrasound penetrates the tissues). Protect your teeth, roots and gums by using Emmi-dent for maximum health and oral hygiene. You may think Emmi-dent is just another electric toothbrush, but it"s a superior cleaning system for everyone! Although sonic and electric toothbrushes are sometimes referred to as ultrasonic brushes, they only spin at about 30,000 mechanical rotations per minute and do not include an ultrasonic chip. Emmi-dent generates ultrasound with a patented ultrasonic microchip that is embedded inside the brush head. This chip creates up to 96 million ultrasonic (air oscillations) impulses per minute and transmits them via the bristles and TheraSol anti-microbial rinse into the gumline giving you a superior cleaning. The ultrasonic impulses are able to penetrate teeth and gums destroying bacteria and germs where bristles can"t reach. This is essential in reducing and protecting against periodontal (gum) disease. Specially formulated nano-bubbles are up to 1000x smaller and are able to reach between the teeth, into the smallest crevices, supporting and enhancing the cleaning effect of ultrasound. We highly recommend using TheraSol with the Emmi-dent brush to deliver antimicrobial solutions deep into pockets for your perio needs.
