Engineers have created the first-ever smartbrush that can clean your teeth in less than three seconds. The patented invention by Nicola Nichele, 28, is a motorised mouth guard that cleans a user's teeth simultaneously. People will spend more than 200 full days manually cleaning their gnashers by following dentists' advice that we spend three minutes after each meal.
