Helps whiten teeth every time you brush

Sonicare electric toothbrush with advanced sonic technology gently removes stains for naturally whiter teeth every time you brush.

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.

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.
