Feel the difference of a gentle clean with Philip's Pressure Sensor while whitening your teeth in 1 week. Click on the W2 Optimal White brush head to remove surface stains and reveal a whiter smile. With its densely packed central stain-removal bristles, it's clinically proven to whiten teeth in just one week. Brushing too hard can damage your teeth and gums. To prevent this, your Philips Sonicare ProtectiveClean emits a gentle pulsing sound to remind you to ease off on the pressure. You can be sure of a safe brushing experience: sonic technology is suitable for use with braces, fillings, crowns and veneers, and helps prevent cavities and improve gum health. Philips Sonicare's advanced sonic technology pulses water between your teeth, and its brush strokes break plaque up and sweep it away for an exceptional daily clean. All brush heads wear out over time. But BrushSync technology tracks how long you've been using your brush head for, and how hard you've been brushing. When it's time to replace it, a light on your handle and a short beep will let you know. That way, you can be sure your brush head is doing a good job. Need an electric toothbrush with a timer? The QuadPacer lets you know when you've spent just the right amount of time cleaning each part of your mouth, while the Smartimer tells you when you've brushed for the recommended two minutes.
