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.

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 15 x healthier in just two weeks**.

Our BrushSync™ feature can remind you when it's almost time for a replacement.

Personalised 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 personalised 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.

Adapts to you in real time when you brush too hard

Most of us apply too much pressure during brushing. That's why our toothbrush automatically adjusts intensity when you push too hard. And with the free Philips Sonicare app, you can experience tailor-made guidance and personalised recommendations to take your brushing to the next level.

Sonic brushing: the masterclass in effective cleaning

Brush away plaque with sonic technology – our benchmark in effective and gentle cleaning. While you brush, up to 62,000 bristle movements and dynamic fluid action help clean even hard-to-reach areas, leaving your mouth feeling exceptionally fresh and clean.
