Senses your brushing style
While you clean, Philips Sonicare 9900 Prestige 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
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.

Philips Sonicare 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.
