Toothbrush­es that smile at you


Okay, so we’re not totally sold on the idea of a gadget that winks and smiles at you when you put it in your mouth. Clearly Douglas Adams wasn’t far off the mark when he predicted doors that would sigh with pleasure when they open. But jokes aside, this toothbrush is crammed with an almost implausibl­e amount of tech. There are different modes (like one for whitening, another for sensitive teeth), 3D tracking of your brushing technique, and alerts when you start scrubbing too hard.
