The Nano-b Toothbrush Uses Gold to Clean Itself

Other “self-cleaning” toothbrushes require a contraption that lives on the top of your sink. You drop the toothbrush in, let the device work its magic, then brush your teeth without grimy bacteria. Cool. But what if you don’t want to clutter up your sink? Or what if you want a clean toothbrush on the road? A smarter method: the Nano-b Charcoal and Gold Toothbrush. The gold integrated into the bristles releases negatively charged ions to suppress bacterial cells, meaning your brush will clean itself every six hours. And when it comes to your pearly whites, the bamboo charcoal also in the bristles acts to naturally whiten and remove stains. It’s a smarter toothbrush for fresh breath and clean teeth.
