Solar Toothbrush Being Tested

Dr. Kunio Komiyama, a Canadian researcher—a "dentistry professor emeritus, no less!—is testing a new "solar-powered toothbrush," which cleans the mouth without the use of any toothpaste.
Komiyama's first model, which was described 15 years ago in the Journal of Clinical Periodontology, contained a titanium dioxide rod in the neck of the brush, just below the nylon bristles. It works when light shines on the wet rod, releasing electrons. Those electrons react with acid in the mouth, which helps break down plaque. No toothpaste is required. Now Komiyama's back with a newer model, the Soladey-J3X, which he says packs twice the chemical punch compared to the original. Protruding from the base of the brush is a solar panel, which transmits electrons to the top of the toothbrush through a lead wire.
The Soladey-J3X is currently undergoing testing by a group of 150 teenagers, whose dark yap holes will be monitored for bacterial levels. Solar toothbrush could make toothpaste obsolete []

    I suspect that’s “leed,” not “led.” :)

    But do people really want to abandon toothpaste? Even if people won’t need it, I’m sure they will still buy toothpaste for their fresh morning and evening mintiness.

    Hmm, now we only need a sonic screwdriver.

    If you’re over about 20, and you’ve ever brushed your teeth without toothpaste, you know WHY you use toothpaste. Your mouth-crud smells like the goop at the bottom of a goldfish bowl.

    So how exactly will this help that?

    Doesn’t seem too smart that they would be using a lead wire in the toothbrush, especially in light of all of the recalls this year.
