Highlights
SenseIQ technology
As you brush, SenseIQ technology senses
pressure, motion, coverage and more up to 100
times per second. It then adapts the intensity i f
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.
Premium All-in-One brush head
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 i n less than two days***. And longer
bristles clean deep for gums that are up to 15x
healthier in j ust 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
The Philips Sonicare app is powered by
artificial intelligence and works in perfect
harmony with the toothbrush. Use i t 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.
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
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 Phili ps Sonicare
app, you can experience tailormade guidance
and personalized recommendations to take
your brushing to the next level.
Cares for your oral health
Phili ps Sonicare 9900 Prestige 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.
Proven sonic brushing
Brush away plaque with sonic technology –
our benchmark in effective and gentle cleani ng.
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.
Real-time feedback
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.
