Japanese scientists are collaborating with an oral health company on a revolutionary toothbrush that uses electricity to make teeth pearly white and does away with the need for toothpaste.

First dreamed up 15 years ago by Dr. Kunio Komiyama, who is now a professor of dentistry at Canada's University of Saskatchewan, the Soladey-J3X has a solar panel at its base that requires minimal amounts of light to transmit electrons to the head of the toothbrush through a titanium dioxide semiconductor embedded in the body.
