The Solidey ionic toothbrush is claimed to be able to clean teeth using only light and water
In Japan and much of Europe, the Soladey toothbrush is nothing new. It was invented 20 years ago, and is currently used by over 16 million people – you may now pause to make a joke about 16 million people all using the same toothbrush. Just recently, however, it has become available in the U.K., U.S. and Canada. What makes it special is the fact that it uses nothing but light and water to clean your teeth.
