The Solar Powered Toothbrush (Japan)

There are so many toothbrushes on the market today. Some fancy features of toothbrushes include rubber grips for your hand, angular bristles, tongue cleaner and of course the motorised toothbrushes.

Well the Japanese company Shiken is currently testing a cool and green toothbrush they invented. It’s a solar powered toothbrush that doesn’t require toothpaste! Sounds cool hey?

How does it work? The Soladey-J3X (Sounds like an anime character) toothbrush has a solar panel at the base that transmits electrons to the top of the toothbrush through a lead wire. The electrons react with the acid in the mouth, creating a chemical reaction that breaks down the plaque and kills bacteria. Interesting, I am a chemist and I really want to know what that reaction pathway is. Does that mean you don’t need to rinse after you brush your teeth?

These toothbrushes have been tested on nefarious bacteria cultures that cause periodontal disease. Results found all the bacterial cells were completely destroyed. Interesting! These toothbrushes don’t consume a lot of energy, which is good... However, standard toothbrushes don’t require any energy at all.

I can think of one major problem for these solar toothbrushes; what happens when you brush your teeth at night and there is no sunlight to charge your toothbrush? I guess the solution to that is: you have to resort back to toothpaste =P
