Riveting news from the world of dental hygiene: The Ultreo ultrasonic toothbrush has officially launched, promising what sounds like the ultimate brush session -- oh you know, "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.
