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 tailormade guidance and personalized recommendations to take your brushing to the next level.
Results you can feel
Cares intuitively for teeth and gums
Philips Sonicare Diamond Clean 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.
Real-Time Feedback
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.
Personalized clean without compromise
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 clean without compromise
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.
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.
