The iO Series 5 uses artificial intelligence to track where you’re brushing in real-time through the Oral-B app, so you never miss a spot. It also features a visible pressure sensor that lights up to let you know if you’re brushing too hard, too soft, or just right (a must-have for anyone worried about their gum health). With five different cleaning settings (including Daily Clean, Whiten, and Sensitive), you can personalize the experience to whatever your teeth need that day. Plus, this bundle includes three brush heads and a travel case.
