fClinically proven to provide superior cleaning. Philips Sonicare's advanced sonic technology pulses water between teeth, and its brush strokes break up plaque and sweep it away for an exceptional daily clean. Densely-packed, high-quality bristles remove up to 3x more plaque than a manual toothbrush. And the contoured bristles fit the shape of your teeth, so you can easily clean those hard-to-reach areas. It takes just 2 minutes to thoroughly brush your teeth. Our QuadPacer lets you know when you've spent the optimal amount of time on each section of your mouth while our SmarTimer signals when your total time is up. Together they help you reach your recommended brushing time, every time. Starting something new can take getting used to. That's why our easy-start program gives you the option of a gradual, gentle increase in brushing power the first 14 times you use your new toothbrush.
