Philips Sonicare ProtectiveClean 4300

white smile. With its densely placed central bristles to remove stains, this brush head clinically proven to whiten your teeth in just one week. You may not notice if you press too hard while brushing, but your toothbrush will. If you put too much strain on your gums, the toothbrush will make a pulsing sound as a reminder to apply less pressure. Safe teeth cleaning: This sonic technology is suitable for use with braces, fillings, crowns and veneers and helps prevent tooth decay and improve the health of your gums. Advanced Philips Sonicare sonic technology flushes water into the interdental spaces and uses brushing movements to loosen and remove plaque for an exceptional daily cleaning result. All brush heads wear out over time. But BrushSync technology remembers how long you've been using your brush head and how hard you brush. When it's time to replace the brush head, a light on the handpiece and a short beep alert you. This way, you can be sure that your brush head will always do an excellent job. 4-quadrant timer tells you when you have spent enough time cleaning each area of your mouth, while 2-minute timer tells you when you have reached the recommended two minutes. A microchip-controlled technology recognizes and synchronizes the intelligent brush head with the intelligent handpiece. The intelligent handpiece and intelligent brush head are a powerful combination. Intelligent reminder functions are possible.
