The Latest Toothbrush That’s Not a Toothbrush: The Emmi-dent uses ultrasonic impulses to do a search-and-destroy on bacteria.
The Emmi-Dent Uses Ultrasonic Impulses to Do a Search-and-Destroy on Bacteria.
Emmi-dent. It’s the toothbrush you’re not supposed to brush your teeth with. But that’s not to say you shouldn’t use it regularly.
Like any other toothbrush, Emmi-dent has a head full of bristles. But they’re for transmitting ultrasonic impulses from a microchip inside the brush head. When these impulses interact with Emmi-dent’s own toothpaste, they cause millions of infinitesimal “nano-bubbles” to form and then collapse. To the bacteria in your mouth, this mass bubble implosion is cataclysmic. The energy released breaks their outer membranes and they die.
“No bacteria equals no plaque, no calculus, no problems,” says Peer Blumenschein, chief executive of Emmi Ultrasonic AG in Basel, Switzerland, the parent company of Emmi-Tech Inc. in Canton, Mass. (Calculus, or tartar, is a hardened form of plaque, and that’s the sticky coating of bacteria you feel on your teeth before brushing.)
