Built-in pressure sensor protects your teeth & 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.

2 minute SmarTimer and 30-second QuadPacer guide you to brush for the recommended time in all areas of your mouth to ensure a complete clean.

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.

Use less. Reuse more

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 year. That’s powerful, right?
