Arrow Product details

Advanced Sonic Technology
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.** 31,000 brush strokes per minute gently clean your teeth, break up plaque, and sweep it away for an exceptional daily clean.

Removes up to 3x more plaque
The Sonicare electric toothbrush with advanced sonic technology is clinically proven to remove plaque up to 3X better* than a manual toothbrush. It removes plaque from your teeth and along the gum line, without being harsh and whilst protecting your gums.

Protect your 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. 

BrushSync replacement reminder
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.

SmartTimer and QuadPacer 
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.

Designed around you 
Slim, light-weight, and ergonomic design makes the toothbrush easy to hold and use so that you can get an amazing clean without any strain.

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

Our Easy-Start program gives you the option of a gradual, gentle increase in brushing power the first 14 times you use your new toothbrush.

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 year. That's powerful, right.
