That little plastic tool you see above could make the dentist’s drill a thing of the past. No more drilling into your teeth, causing pain and making you nervous. The DMG Icon delivers a small amount of hydrochloric acid directly on the cavity and burns away just the right amount of enamel to reach the area where the cavity is eating away at your tooth.

Once that’s done, the dentist uses a separate applicator to inject quick-hardening resin-type goo into the hole, and then with a short zap of high-energy blue light, it hardens so well that your tooth is as good as new. Sounds too good to be true, but if it really works that well it could make dental visits happier.

Problem is that the technology doesn’t work on chewing surfaces yet. They expect a new version capable of that will be ready in a year. This one only works on early-stage cavities.
