Dental Professional recommended sonic toothbrush brand worldwide
Sonic technology, combined with the brush, gently removes up to 7 times more plaque1 than a manual toothbrush.
Removes up 7x more plaque vs a manual toothbrush
Sonicare electric toothbrush with advanced unique technology is clinically proven to remove up to 7x more plaque from your teeth and along the gum line while protecting your gums.
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.
Optimize your brushing with SmarTimer 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.
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
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.
Switch between 2 intensity settings
Switch between 2 intensity settings to make the brushing session comfortable for you.
