There are a few things that you need to do for good oral hygiene and these include brush and floss daily as well as having regular dental checkups. With regards to brushing your teeth, there are a number of choices when it comes to toothpaste.

You can buy toothpaste that is specially designed for tooth whitening or perhaps one that is specific for reducing tooth sensitivity. Regardless of what type of toothpaste you buy, toothpaste is a given part of this equation, at least for now.

There’s a new research study being undertaken at the University of Saskatchewan by professors Dr. Kunio Komiyama and Dr. Gerry Uswak who are looking at a new solar toothbrush that will eliminate the need for toothpaste. The new toothbrush, Soladey-J3X, which has been manufactured by the Japanese company Shiken is the second generation design building on the original model that was developed some 15 years ago. The original model used a titanium dioxide rod just under the nylon bristles of the brush. When light shines on the wet rod, it causes a chemical reaction in which negatively charged electrons are released. These electrons interact with the normal acid found in the mouth which subsequently attacks plaque. In the process, no toothpaste is needed.

The new model that the professors are working on has twice the chemical power of the predecessor and also utilizes a solar panel which moves electrons to the toothbrush head through a lead wire. As a solar powered toothbrush, Soladey-J3X will not work in the dark, but it only needs as much light as a small solar calculator.
