Your dentist just got a powerful new sidekick — and no, we're not talking about that weird suction device he uses to remove all your spit, that's old news. The Kolibree Smart Toothbrush ($TBA) is the only existing app-connected toothbrush (for now), and that makes it better. Much better. So, for those of you who couldn't remember to brush your teeth twice a day, or if you forget the most important parts of your mouth on a regular basis, this one's for you. It does all the remembering — and nagging — for you, alerting you via a mobile app when it's time to brush again, tracking your brushing effectiveness, and charting your progress over time. It'll even send updates to your dentist or share them with your family, in case you need a little added reinforcement.
