Emmi-tech offers the Emmi-dent Ultrasonic Toothbrush that whitens teeth without bleach or other chemicals. Ultrasound technology kills bacteria from food and drink that cause teeth stains. It restores the teeth to their natural color and prevents inflammation, periodontitis and bad breath. Motionless ultrasonic cleaning—used with its nonabrasive toothpaste—produces
96 million air oscillations per minute with no abrasion and no damage to the teeth and gums.
