Boie USA's black toothbrush makes oral hygiene look cool.

"We've embedded silver into the bristles and head that helps kill bacteria.  The heads last long too, up to two times longer than the kind of toothbrush you've been using your whole life. Less waste because it doesn't use batteries and the heads are interchangeable. This means you can keep your handle and use it for as long as you want. Oh yea, did we mention that it's better for you too? Our bristles are made from a rubber-like material that is less abrasive on your enamel and gums. BPA and Phthalate-free."
