The Oral-B Genius 10000N Limited Black Design Edition features Oral-B's smartest cleaning system, which helps you clean the way your dentist recommends. The innovative gum protection assistant shows you the areas where you exert too much pressure to prevent gum problems. The toothbrush is compatible with the Oral-B App and gives you feedback for a smoother routine. In addition, the visual pressure control with the help of the personalizable SmartRing reminds you when you exert too much pressure and automatically reduces the cleaning speed. With the unique position detection technology and round brush head, you'll never forget an area and remove up to 100% more plaque than with a conventional manual toothbrush.
