Toothbrush that doesn’t allow shortcutsComment on this story
Las Vegas - A smart toothbrush that can tell you if you’ve missed a spot when you brush is expected to go on sale later this year.
The Kolibree toothbrush is filled with sensors, and uses an app to show people exactly where they have brushed.
Information on the time, the motion, and how far back in your mouth you get during brushing is sent via bluetooth to a smartphone.
The device was unveiled at the Las Vegas show and is due to be on store shelves some time after April.
