SenseIQ technology senses, adapts and cares

SenseIQ technology senses, adapts and cares

As you brush, SenseIQ technology senses pressure, motion, coverage and more up to 100 times per second. It then adapts the intensity if you push too hard. The intelligence of SenseIQ takes the guesswork out of brushing modes, so you can experience effortless care and better brushing over time.

All-in-One brush head for complete care

All-in-One brush head for complete care

Clean without compromise with the A3 Premium All-in-One brush head. Our all-time best has angled bristles to help remove up to 20x more plaque even in hard-to-reach areas*. Triangular tips work to remove up to 100% more stains in less than two days***. And longer bristles clean deep for gums that are up to 15x healthier in just two weeks**. All that without ever switching brush heads. Did you know: brush heads become less effective after 3 months of use? Our BrushSync™ feature can remind you when it's almost time for a replacement.

Personalized guidance from the Philips Sonicare app

Personalized guidance from the Philips Sonicare app

The Philips Sonicare app is powered by artificial intelligence and works in perfect harmony with the toothbrush. Use it to brush with real-time guidance about pressure, motion, coverage, duration and frequency. View progress reports by day, week, month and year. Get personalized recommendations and actionable steps for better brushing. Meanwhile, auto-syncing keeps brushing data up-to-date in the app, even when you don’t brush with the app by your side.
