Highlights

Advanced Sonicare Technology

Powerful brush head vibrations create micro-bubbles that reach deep between teeth and along the gumline for a refreshing clean. Achieve a whole month's worth of manual brushing in just 2 minutes**. With over 31,000 brush strokes per minute, it gently cleans teeth, breaks up plaque, and removes stains for superior daily oral care.

Protect Your Gums

The built-in pressure sensor automatically detects and alerts you when you're brushing too hard, reducing the brush's vibration to protect your gums. The toothbrush will emit a pulsing sound as a reminder to ease pressure. 7 out of 10 users found this feature helped them brush better.

BrushSync Replacement Reminders

Brush heads wear out over time, so you'll want to replace yours to ensure optimal cleaning. BrushSync technology tracks your brush head usage and intensity, alerting you via an icon on the handle and short beeps when it's time for a replacement.
