The Oral-B Genius 10000N Limited Black Design Edition features Oral-B's most intelligent brushing system, helping you brush as your dentist recommends. The innovative gum pressure assistant shows you areas where you apply too much pressure, preventing gum problems. The toothbrush is compatible with the Oral-B app and provides feedback for a gentler routine. Additionally, the visual pressure control, using the customizable SmartRing, reminds you when you are applying too much pressure and automatically reduces the brushing speed. With the unique position detection technology and the round brush head, you'll never miss a spot again and remove up to 100% more plaque than with a conventional manual toothbrush.
