Ultreo toothbrush

The Ultreo ultrasonic toothbrush promises what sounds like the ultimate brush session -- "ultrasound waveguide technology" and "precisely tuned sonic bristle action" and stuff like that.

Unlike traditional sonic units that only use audible frequencies of 20Hz to 20,000Hz, Ultreo uses a tuned sonic / ultrasonic (over 20,000Hz) combo to offer more enamel-rattling power without compromising the user's veneers, bridges, or general safety. There's a programmable replacement indicator that prompts a brush head switch-out every 3 months, and the 2-minute auto shut-off timer makes sure you don't cop out too early.
