Use the Oral-B App to seamlessly pair your Genius 8000 with a smartphone and you're on your way to brushing like your dentist recommends. The Oral-B Genius 8000 comes with Position Detection technology which uses Bluetooth technology, your smartphone, and facial recognition technology to provide you with real-time feedback about your brushing habits. The 360 Smarting with LED lights allows you to personalize your brushing experience with your choice of 12 colors. The Smarting works with the integrated timer and pressure sensor to provide you with visual feedback on brushing time and brushing pressure. Together, they help you ensure you brush for the recommended 2-minutes while making sure you brush with appropriate pressure to protect your gums from over-brushing. The premium Smart Travel Case lets you charge your brush and smartphone (via USB) at the same time while using only one wall plug. The Genius features 6 brushing modes so you can further customize your brushing experience based on your specific oral care goals. This highly advanced brush features a dentist-inspired round head that surrounds and cups each tooth with dynamic oscillating, rotating and pulsating movements to remove up to 500% more plaque than a regular manual toothbrush. Trust in the precision engineering of Braun and the dental expertise of Oral-B, the #1 brand used and recommended by dentists worldwide. 100% Satisfaction Guaranteed.
