Could The Light-Powered Toothbrush Mean the End of Toothpaste?

Light Powered ToothBrushBrushing our teeth is an action we do on a daily basis. Besides the need of a toothbrush, the toothpaste is just as important in the action of brushing our teeth.

But what would happen if the toothpaste would be obsolete? What if it was no longer needed? Imagine brushing your teeth without the need of toothpaste.

The Shiken Company of Japan is seeking to combine further technology towards advanced dentistry. One current project is a solar-powered toothbrush, which may do the proper task without the need of toothpaste; a chemical reaction is created to help eliminate harmful plaque and bacteria.

Dr. Komiyama, the original designer of this toothbrush explained that “…it contained a titanium dioxide rod in the neck of the brush, just below the nylon bristles. Any light falling on the wet rod would release electrons, which would react to the acid typically found in the mouth, helping break down plaque”. In short, an alternative for toothpaste.

The latest model, the Soladey-J3X, is twice as powerful and requires only as much light as a solar-powered calculator does.
