Philips' Sonicare takes toothbrushes to the next level by adding radiation into the mix. After you're done brushing your teeth, remove the head from the brush and seal it in the chamber. With one button press, the sanitizer bathes the head with UV radiation, sterilizing the bristles and preventing germ buildup...and toasting your brush.

Available in August for $180. (via SCI-FI Tech)
