Next-Generation Sonicare Technology
The toothbrush utilizes advanced sonic technology, providing 62,000 bristle movements per minute. The motor automatically adjusts power to maintain consistent performance, even in hard-to-reach areas. Sonicare Fluid Action supports the bristles by driving fluid deep between teeth and along the gumline for effective cleaning.


SmarTimer and BrushPacer
The built-in SmarTimer ensures you brush for the dentist-recommended 2 minutes. The BrushPacer prompts you to move to a new section of your mouth every 20 seconds, ensuring thorough cleaning of all areas.

Visual Pressure Sensor
To protect your gums, a visual pressure sensor at the base of the toothbrush handle will light up if you apply too much pressure. Reduce pressure when the light activates.

Sonicare App Integration
Connect your toothbrush to the Sonicare app for guided brushing, tips, and personalized content to help achieve your oral health goals.
