Here’s something to smile about. A unique cooperative Arab-Jewish incubator in Nazareth, Israel claims to have a method that will keep you away from the dentist and help you retain your pearly whites.

The start-up, Fluorinex, is developing “a small device which together with a gel will impose an efficient ion exchange process through an Electro-chemical reaction in which fluor ions displace the Hydroxide ions at the outer layer of the tooth.” Essentially you’re electroplating your teeth. But not with bling, rather a harder enamel. Put this device in your mouth, plug it into a wall outlet, and ZAP!! –No more cavities for 5 years.
Although it’s less effective, I’d recommend anyone trying this stick with the battery-powered version till they get the kinks out.
