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.

Cares intuitively for teeth and gums

Cares intuitively for teeth and gums

Philips Sonicare DiamondClean Prestige 9900 is designed around you. Its state-of-the-art technology is so in tune with you and effortless to use that you barely know it is there. Luckily, the results say it all.

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 20 x 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 15 x 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.

Personalised guidance from the Philips Sonicare app

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.

Senses your brushing style

Senses your brushing style

While you clean, Philips Sonicare DiamondClean Prestige 9900 uses sensors to detect the pressure you apply, cleaning motion and coverage up to 100 times per second. The sensors also keep an eye on how long and how often you brush.

Adapts to you in real time when you brush too hard

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

Real-time feedback on your brushing

Real-time feedback on your brushing

You might not notice when you brush too hard or start scrubbing, but your toothbrush will. The light ring on the end of your handle will gently remind you to ease off the pressure or scrubbing motion.
