Brushing your teeth is a regular ritual for most people, and normally that involves both a toothbrush and toothpaste to remove the gunk that builds up on our teeth and gums. The solar toothbrush looks to eliminate the paste, harnessing the power of the sun to kill off all that nasty bacteria.The Shiken Soladey-J3X had a small solar panel near its base, which creates a stream of electrons that are emitted the head and react with acid in your mouth. Developers Dr. Kunio Komiyama and Dr. Gerry Uswak say that this results in "complete destruction of bacterial cells."
My concern is that bacteria isn't the only thing brushing takes care of. Most toothpastes include fluoride to fight cavities, and compounds to help remove any plaque deposits. If you get rid of the paste, will these problems become worse?
The Solidey-J3X is currently undergoing field trials.
