The Oral-B Precision Black 7000 is in a class of its own. \r
Its what happens when German engineers have a zero tolerance for plaque. It accelerates to top speed faster than a high performance sports car. Seven independent functions. Up to 800 brush movements per second. Designed by Braun, it truly is engineered to perform. Six High-Performance Brushing Modes: Daily Clean, Deep Clean, Whitening, Massage, Sensitive and Tongue Cleaning. Sophisticated pressure-sensor technology alerts you if youre brushing too hard and automatically decelerates the pulsation and oscillation speeds of the brush head. Wireless SmartGuide gives you real-time information about brushing modes, times and areas. Specially designed seals and gaskets keep the Oral-B Black water tolerant to 500 millibars of pressure. Made of different high-tech materials like silicon, the black travel case protects all of its vital technology. Designed by the engineers at Braun, it removes up to 100% more plaque than a regular manual brush.
