Solar Powered Toothbrush by Dr. Kunio Komiyama
Dr. Kunio Komiyama, a dentist at the University of Saskatchewan College of Dentistry in Canada, designed a new “solar-powered toothbrush” that cleanses the mouth without using toothpaste. When the light strikes wet titanium dioxide head more electrons being released, which are negatively charged fluid inside the mouth that can remove hydrogen ions from the plaque, making it easier to break down. No toothpaste is necessary. Currently, Komiyama is back with a newer model, Soladey-J3X, which he said pack twice the chemical punch than the original.
