The Oral-B Genius 10100S is the winner of Stiftung Warentest (Test 11/2017). This first intelligent brushing system from Oral-B helps you brush as your dentist recommends. The innovative gum protection assistant shows you the areas where you apply too much pressure to prevent gum problems. It 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 brushing too hard and automatically reduces the brushing speed to protect your sensitive gums. With unique position detection technology and a round brush head, you'll never miss a spot again and remove up to 100% more plaque than with a conventional manual toothbrush. The Genius 10100S also features a lithium-ion battery that lasts over 2 weeks on a single charge. The premium charging travel case allows you to charge your smartphone and toothbrush using just one outlet. With the Oral-B Genius 10100S, you can't go wrong while brushing. It's no wonder that Oral-B is the brand most recommended by dentists worldwide. The Oral-B Genius 10100S is available in black, white, and orchid purple. It can be used with the following Oral-B brush heads: CrossAction, 3DWhite, Sensi UltraThin, Sensitive, Precision Clean, Deep Clean, TriZone, and Ortho Care.
