    Pressure Sensor helps protect your teeth and gums

    Built-in pressure sensor automatically detects pressure you apply, warns you, and 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. 7 out of 10 people found this feature helped them become better brushers.

    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. You will get two month's worth of manual brushing in just 2 minutes.** 31000 brush strokes per minute gently clean your teeth, break up plaque, and sweep it away for an exceptional daily clean.

    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.

    14-day long lasting battery life

    Battery life lasts up to 14 days so you can go long periods without charging.

    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?
