The Philips Sonicare Series 4100 Electric Toothbrush in Malibu Blue with advanced sonic technology and W1 optimal white brush head gently removes stains for naturally whiter teeth every time you brush. Advanced Sonicare Technology creates powerful bristle vibrations that drive microbubbles deep between your teeth and along your gum line while protecting your gums for a refreshing experience. You will get one month's worth of manual brushing in just 2 minutes. 31,000 brush strokes per minute gently clean your teeth, break up plaque and sweep it away for an exceptional daily clean. The built-in pressure sensor detects the pressure you apply, not only warns you but reduces the toothbrush vibrations automatically to help protect your gums. The toothbrush will make a pulsing sound as a reminder to ease off the pressure. The Philips Sonicare Series 4100 electric toothbrush comes with two modes, Clean and Sensitive. You can switch between the two modes to tailor the brushing session to you. This electric toothbrush also features the 2-minute SmartTimer which ensures you brush for the dentist-recommended time and the 30-second QuadPacer which guides you to brush each quadrant of your mouth evenly for a complete clean. As all electric toothbrush heads wear out over time, the BrushSync technology helps you track how long you've been using your brush head for and how hard you've been brushing. The BrushSync replacement reminder will alert you with a short bleep when it's time to replace it. Philips Sonicare toothbrush heads are recyclable via the Philips dental care recycling program in partnership with TerraCycle, allowing you to recycle your used Philips Sonicare toothbrush heads responsibly, contributing to a greener planet. The Philips Sonicare Series 4100 is the perfect choice for switching from a manual to an electric toothbrush. Ergonomically designed for your comfort, its slim and lightweight build ensures it is easy to hold and use, providing an exceptional clean without any strain.
