I’m a little behind the times, but just came across this great article about a toothbrush that uses solar power to clean teeth rather than toothpaste. Way cool.

And where does it come from? Saskatoon of course! Love those Canadians! The manufacturer is Japanese so it’s a joint effort, I guess. Apparently, the idea has been around for 15 years but they’re now calling for trialists. Obviously, you can’t use it in the dark, but apparently, it only needs as much light as a solar powered calculator to operate.

The toothbrush itself uses a titanium dioxide rod which releases electrons when it’s wet and light shines on it. The electrons then react with acid in the mouth (acid being the big bad guy when it comes to cavities). Very nifty. And who’d have thought dentistry could be so interesting?
