SenseIQ: Artificial intelligence for personalised cleaning
The most advanced Philips toothbrush model combines advanced technology, a unique brush head shape, and the ability to adapt to your individual needs. SenseIQ technology analyses the way you brush your teeth and gums and provides personalised recommendations via an app for even more effective care. It works just like a consultation with a dental hygienist—with the difference that you have professional, tailored care available every day, right in your own bathroom.
Advanced SenseIQ technology for gentle care
An individual approach with 15 setting options
Removes up to 20× more plaque*, up to 15× healthier gums***
Reliable sonic technology
Effectively get rid of dental plaque thanks to sonic technology. The high-frequency movement creates a dynamic wave that breaks up plaque and pushes it into the spaces between teeth and along the gum line. The toothbrush performs up to 62,000 gentle but highly effective strokes per minute. It is safe and suitable for use with braces and can be used on fillings, crowns, and veneers.
SenseIQ Technology
While you brush, the toothbrush scans the pressure, range of motion, and other key parameters up to 100 times per second and instantly evaluates the data. This ensures you can rely on the correct brushing technique, precisely tailored to your needs, for a truly personalised experience. The result is easy, professional care and progressively more effective teeth cleaning.
Sonicare 9900 senses and adapts
Thanks to artificial intelligence and SenseIQ technology, the DiamondClean Prestige 9900 actively adapts to your brushing technique and continuously optimises it. Operation is as simple as possible—the toothbrush has a single button for turning it on and off. Based on your needs, it automatically selects the most suitable cleaning mode, so there's no need to switch anything manually. The Clean and Deep Clean modes focus on effective plaque removal, White+ helps to reduce tooth staining, Gum Health supports gum health, and the Sensitive mode provides exceptionally gentle cleaning. The toothbrush also adjusts the intensity level to be just right for you.
Comprehensive oral care
The most thorough clean, without compromise. The toothbrush with the Premium All-in-One head removes up to 20× more dental plaque, even in hard-to-reach areas. It restores a brighter look to your teeth, managing to remove up to 100% more stains in just 2 days. It also contributes to improving gum health—up to 15× healthier gums in just 2 weeks. Discover a whole new feeling of perfectly clean teeth and fresh, healthy gums.
Intelligent toothbrush sensors
The DiamondClean Prestige 9900 toothbrush can instantly alert you to incorrect brushing technique. If you apply too much pressure, the light ring at the end of the body will light up purple and the toothbrush will gently vibrate to let you know you need to ease off. If you're scrubbing your teeth too hard, the light ring will turn amber and a vibration will guide you towards a gentler motion. Thanks to this immediate feedback during brushing, you can easily improve your technique and achieve more effective and gentler care for your teeth and gums.
Cleaning with feedback
The Philips Sonicare app highlights problem areas on a 3D map of your mouth and reminds you to pay more attention to these areas. The app will alert you when you have achieved a perfect clean and advise you on how to brush better and more thoroughly. The TouchUp feature will guide you back to any missed areas. Cleaning reports are saved directly in the app, where you can review them later. All data is automatically synchronised and updated, even if you don't have your phone with you while brushing.
Synchronisation and head replacement
The toothbrush head gradually wears out and its effectiveness at removing plaque decreases. Thanks to intelligent BrushSync technology, the toothbrush automatically recognises when it's time to replace the head. Sensors track how long and how carefully you've been brushing and alert you at the optimal moment for a replacement. For maximum effectiveness, we recommend changing the head approximately every 3 months.
Useful timers
The Smartimer tracks the recommended minimum cleaning time of 2 minutes and alerts you when the time is up. The BrushPacer guides you to spend enough time on each part of your mouth—divided into four quadrants. Thanks to them, your teeth cleaning is effective and perfectly timed.
Stylish storage and charging
An indicator light on the toothbrush body will alert you to a low battery. While travelling, you will appreciate the compact travel case with USB charging, which is made from soft-touch vegan leather and keeps the toothbrush safe. For home charging, there's an elegant puck-shaped base that combines style and practicality.
