Solar Toothbrush Makes Toothpaste Obsolete.

Is the future of oral hygiene solar? Are we ever going to stop depending on toothpaste? Will we be using solar power instead of toothpaste one day? In Japan, the Shiken company is trying to give answers to these questions by field testing an unusual solar-powered toothbrush that doesn’t require toothpaste.

The Soladey-J3X is a solar-powered toothbrush designed by Dr. Kunio Komiyama (dentistry professor at the University of Saskatchewan) and Dr. Gerry Uswak. The first model was designed 15 years ago (it was described in the Journal of Clinical Periodontology) and more work has been done since then in order to perfect it.

Now, Komiyama is back with a new model, the Soladey-J3X, which he says packs twice the chemical punch compared to the original.
It is a solar-powered toothbrush with a solar panel at its base that transmits electrons to the top of the toothbrush through a lead wire.

These electrons react with acid in the mouth, creating a chemical reaction that breaks down plaque and kills hazardous bacteria. This means no toothpaste is required – helping you save more money in the long run (as well as water, since there is less rinsing to be required).

Researchers have already tested the toothbrush in cultures of nefarious bacteria that cause periodontal disease. The solar-powered brush caused complete destruction of bacterial cells.

How much power does the Soladey-J3X need to be effective? To get fully charged this toothbrush needs only as much sunlight as a solar-powered calculator.

The Soladey-J3X won the first place prize out of 170 entries at the annual FDI World Dental Conference in Dubai last month. This gives Komiyama confidence that there is scientific merit to the brush.
