Oral-B iO Series 9 Electric Toothbrush with 3 Replacement Brush Heads ($256, originally $300)
This electric toothbrush will change any preconceived ideas you have about electric toothbrushes forever. Download the accompanying app and you can watch (in real time!) as you brush and are provided with smart feedback, which identifies your pressure and lets you know when to ease up. The app will also let you know when you've successfully cleaned one section of your mouth and can move on to the next via a light-up infographic. If that's not enough to leave you mind-blown, the device features up to seven brush modes, along with a smart display that greets you, motivates you as you brush, and keeps time count on your job. The brush head itself combines oscillating, rotating movements with micro-vibrations to reach every contour of your teeth.
