    Our unique technology brings you a powerful yet gentle clean

    Powerful bristle vibrations drive microbubbles deep between your teeth and along your gum line for a refreshing experience.

    Always know when to replace your brush heads

    Always know when to replace your brush heads

    All brush heads wear out over time, so you'll want to keep an eye on yours to make sure you're still getting a great clean. Our BrushSync technology tracks how long you've been using your brush head for, and how hard you've been brushing. The BrushSync replacement reminder on your handle and a short beep gives you a heads up when it's time to replace it.

    Goodbye adapter. Hello USB.

    Goodbye adapter. Hello USB.

    Power adapters may seem small, but added together, their plastics make a huge impact on the environment. By switching to USB charger in our Philips Sonicare 1000-4000 Series alone, we can use up to 189,210 kg less plastic every 4 years. That's powerful, right?
