The unique position detection technology helps you to brush all areas of your mouth while Oral-B's unique round head does all the rest. It removes up to 100% more plaque compared to a regular manual toothbrush for healthier gums and makes your smile whiter starting from first day of brushing by removing surface stains. Not only this, but the toothbrush helps you protect your delicate gums with the proprietary SmartRing and pressure control technology that reduces brushing speed and alerts you to be gentler if you brush too hard. With Oral-B Genius 8000, you can't go wrong in brushing. No wonder Oral-B is the Number 1 recommended brand by dentists worldwide.
