The Soladey-3 uses a novel method to remove plaque.

The Japan Trend Shop has an interesting product in its catalog called the Soladey-3 which doesn’t use toothpaste to remove plaque. Soladey-3 has an embedded solar panel that absorbs light; when a user begins to brush his teeth, the electrons are transmitted through the water to the teeth via a titanium oxide semiconductor to make the plaque unstable and easy to remove.
