Solar Powered Toothbrush…No Toothpaste Needed

Now that we don’t need soap for our dishes and we also don’t need to replace our razors nearly as often, a similar technology has come to toothbrushes.  Actually, the technology has been around for about 15 years.

Dr. Kunio Komiyama and his colleague Dr. Gerry Uswak are testing 120 Canadian teenagers willing to brush with the solar powered toothbrush and go to the dentist more frequently to document the effectiveness of the toothbrush.

Fifteen years ago, the first model introduced a titanium dioxide rod embedded in the neck of the brush just below the nylon bristles.  Light activates a wet rod thereby releasing electrons which react with acid in your mouth.  This helps to break down plaque without the use of toothpaste.

The newest model, the Soladey-J3X, is twice as effective as the old model.  The Soladey will not work in the dark, but it only needs about as much light as a solar calculator.  Although the tests on the new model are ongoing, lab tests showed complete destruction of two types of bacteria which are major culprits in periodontal disease.
