Experience a brighter clean with the Philips Sonicare 4100, which uses sonic technology to lift surface stains and improve gum health.

The BrushSync feature alerts you when to replace the head for optimal performance.
Start your day with a brighter clean. The Philips Sonicare Series 4100 Electric Toothbrush uses sonic technology with 31,000 pulsations per minute to lift surface stains and drive microbubbles deep between teeth and along the gumline. It includes a W1 Optimal White brush head and two modes - Deep Clean and Sensitive, plus a pressure sensor that alerts you with a pulsing sound when you brush too hard and reduces vibrations to protect gums. BrushSync tracks brush head use and alerts you when to replace it. A 2-minute timer and 30-second QuadPacer keep you on track. The sonic action delivers a month of manual brushing in just 2 minutes for a refreshing clean every time. The pressure sensor takes the guesswork out of safe brushing by reducing power when needed, so you always get an effective clean without overdoing it. The rechargeable battery lasts up to two weeks on a full charge, ideal for everyday use or travel.
