Effective personalized cleaning!

The Sonicare 9900 Prestige equipped with SenseIQ technology is our most powerful and sophisticated electric toothbrush yet. It enhances our Sonic technology by intelligently adapting and providing comprehensive cleaning.

SenseIQ Technology

While you brush, the SenseIQ technology measures factors like how much pressure you apply, the movement of the toothbrush, and the coverage of the cleaning up to 100 times per second. If you exert excessive pressure, it decreases the intensity. The intelligent SenseIQ determines suitable brushing modes, allowing you to enjoy worry-free oral care and better brushing results.

Premium All-in-One Brush Head

Clean your teeth without compromise with the A3 Premium All-in-One brush head. In our best model to date, the angular bristles remove up to 20 times more plaque even from hard-to-reach areas*. The triangular tips help eliminate up to 100% more stains in under two days. Longer bristles clean the gums deeply, resulting in gums up to 15 times healthier in just two weeks, all without changing brush heads. Did you know that brush heads lose their efficacy after 3 months of use? Our BrushSync function reminds you when it’s time for a replacement.

Personalized Guidance

The AI-powered Philips Sonicare app seamlessly integrates with the toothbrush. While you brush, you receive real-time guidance on toothbrush pressure, movement, cleaning coverage, duration, and regularity. Track progress reports daily, weekly, monthly, or annually. Get personalized recommendations and instructions for better oral hygiene. Automatic synchronization keeps brushing data up to date in the app even when you’re brushing without it.

Recognizes Your Brushing Style

As you clean your teeth with Philips Sonicare 9900 Prestige, it tracks how much pressure you apply, how you move the brush, and the thoroughness of cleaning—up to 100 times per second. The sensors also monitor how long and how often you brush your teeth.

Adapts in Real-Time

Most of us apply too much pressure while brushing teeth. That’s why our toothbrush adjusts the brushing intensity automatically if you exert excessive pressure. With the free Philips Sonicare app, you receive personalized advice and recommendations for better dental care.

Cares for Your Oral Health

The Philips Sonicare 9900 Prestige is designed for your needs. Its cutting-edge technology adapts to your usage so seamlessly that you might hardly notice it. Fortunately, the results are even more noticeable.

Remove plaque with sonic technology – experience advanced and gentle cleaning. Up to 62,000 brush movements and dynamic fluid action help clean even the hardest-to-reach areas, leaving your mouth exceptionally fresh and clean. Removes 20 times more plaque than a manual toothbrush.
