Attractive, compact design
With the Sonicare 9900 Prestige toothbrush, you can take the greatest results of technology in a stylish and compact design. This toothbrush is 18mm shorter than the DiamondClean toothbrush and is made from high-quality materials for an eye-catching and pleasant feel.

SenseIQ senses, adapts and nurtures
While brushing, SenseIQ technology detects pressure, movement, coverage and more up to 100 times per second. If the pressure is too strong, adjust the intensity. The intelligence of SenseIQ does not leave the cleaning mode to chance, so you can enjoy the experience of effortless oral care and more efficient cleaning for a long time.

It adjusts to you in real time if you brush too hard
Most people use too much pressure when brushing their teeth. Our toothbrush therefore automatically adjusts the intensity if you brush too hard. And with the free Philips Sonicare app, you can get personalized guidance and suggestions to take your brushing to the next level.

Intuitively cares for teeth and gums
The Philips Sonicare Prestige 9900 is designed with your needs in mind. Its state-of-the-art technology adapts to you so well and is so easy to use that it's almost unnoticeable. Fortunately, however, the results speak for themselves.

It senses the way you brush your teeth
The Philips Sonicare 9900 Prestige's sensors detect the pressure you apply, the brushing movements and the coverage during brushing - up to 100 times per second. The sensors also detect the duration and frequency of cleaning.

Real-time feedback on brushing
You may not even notice if you brush or rub your teeth too hard, but your toothbrush will. A ring of light at the end of the handle gently alerts you to ease off pressure or rubbing movements.

Sonic cleaning: the high school of effective brushing
Remove plaque with sonic technology – the benchmark for effective and gentle teeth cleaning. During brushing, up to 62,000 cleaning movements made by the bristles and dynamic liquid cleaning help to clean even hard-to-reach areas, thus ensuring a feeling of extreme freshness and cleanliness in the mouth.

All-in-One brush head for perfect care
Clean without compromise with the A3 Premium All-in-One brush head. Thanks to its angled bristles, our best toothbrush to date removes up to 20 times more plaque, even from hard-to-reach places*. Triangular bristle tips remove up to 100% more discoloration in just two days***. And the longer bristles thoroughly clean the gums, which become up to 15 times healthier after just two weeks**. All this without changing the brush heads even once. Did you know that brush heads become less effective after 3 months of use? However, the BrushSync™ function will remind you shortly before the replacement.

Personalized guidance in the Philips Sonicare app
Powered by artificial intelligence, the Philips Sonicare app works in perfect harmony with your toothbrush. Use it to get real-time brushing assistance and advice on pressure, strokes, coverage, duration and frequency. You can view daily, weekly, monthly and yearly progress reports. Personalized recommendations and actionable steps for better cleaning. Meanwhile, automatic synchronization keeps brushing data up-to-date in the app, even if you don't have the app with you when you brush your teeth.
