Features

Designed Around You

Always know when to replace your brush head

All brush heads wear out over time, and BrushSync™ technology keeps track of both usage duration and brushing pressure. When it’s time to replace your brush head, the handle and a short beep alert you—so you always get the best clean.

Switch between 2 intensity settings

Choose between two intensities to create the brushing experience that feels most comfortable for you.

14-day long-lasting battery life

Enjoy up to 14 days of use on a single charge—perfect for home or travel without constant recharging.

Optimize Your Brushing

SmarTimer & QuadPacer for complete coverage

The 2-minute SmarTimer and 30-second QuadPacer guide you through the dentist-recommended brushing routine, ensuring every area of your mouth gets a thorough clean.

Protects Your Gums

Pressure Sensor helps prevent overbrushing

The built-in pressure sensor automatically detects when you're brushing too hard, then alerts you with a pulsing sound while reducing brush vibrations.

7 out of 10 users reported this feature helped them brush more effectively and gently.

Provides a Superior Clean

Powerful yet gentle Sonicare technology

High-speed bristle vibrations create microbubbles that reach deep between teeth and along the gumline.

In just 2 minutes, you get the cleaning equivalent of two months of manual brushing.

With 31,000 brush strokes per minute, the brush gently breaks up and sweeps away plaque for an exceptional daily clean.

Up to 7x better plaque removal*

Clinically proven Sonicare technology removes up to 7x more plaque along the gumline compared to a manual toothbrush—while remaining gentle on gums.
