The Philips Sonicare Series 4100 Electric Toothbrush in White 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.

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 comes with two modes, Clean and Sensitive, to tailor the brushing session to you.

It 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.

BrushSync technology helps you track how long you've been using your brush head for and how hard you've been brushing, alerting you when it's time to replace it.

Philips Sonicare toothbrush heads are recyclable via the Philips dental care recycling program in partnership with TerraCycle.

The ergonomically designed toothbrush is slim and lightweight for easy use, with an Easy-Start program for a comfortable transition from manual to electric brushing.

It has a long-lasting battery life of up to 14 days on a single charge, making it ideal for travel.
