Pressure Sensor helps protect your teeth and gums

Pressure Sensor helps protect your teeth and gums

Built-in pressure sensor automatically detects the 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 months' 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.

Optimise your brushing with SmarTimer and QuadPacer

2 minute SmartTimer 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

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 remind you when it's time to replace it.
