Philips Sonicare 9900 DiamondClean Prestige HX9992/31 + HX9992/42 Electric Toothbrush
SenseIQ: Artificial intelligence for tailor-made cleaning
The most advanced Philips toothbrush combines sophisticated technology, a unique head shape, and the ability to adapt to your individual needs. SenseIQ technology analyses the way you brush your teeth and gums, providing you with personalised recommendations for even more effective care via the app. It works like a consultation with a dental hygienist, except that this professional, tailor-made care is available every day, right in your own bathroom.
Advanced SenseIQ technology for gentle care
Individual approach thanks to 15 setting options
Removes up to 20× more plaque* and gives you up to 15× healthier gums***
Reliable sonic technology
Effectively remove plaque thanks to sonic technology. High-frequency vibrations create a dynamic wave that disrupts plaque and pushes it into the spaces between your teeth and along the gumline. The Philips Sonicare 9900 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 Philips Sonicare 9900 senses pressure, motion, and other key parameters up to 100 times per second, and instantly analyses the data. This ensures you can rely on the correct brushing technique, tailored precisely to your needs, for a truly personalised experience. The result is easy, professional care and progressively more effective brushing.
The Philips Sonicare 9900 electric toothbrush optimises your brushing
Thanks to artificial intelligence and SenseIQ technology, the DiamondClean Prestige 9900 actively adapts to and continuously optimises your brushing technique. Operation is extremely simple – the toothbrush has a single button to turn it on and off. It automatically selects the most suitable cleaning mode based on your needs, so there's no need to switch anything manually. The Clean and Deep Clean modes focus on effective plaque removal, White+ helps reduce tooth discolouration, Gum Health promotes gum health, and the Sensitive mode provides exceptionally gentle cleaning. The Philips Sonicare 9900 also adjusts the intensity level to suit you perfectly.
Comprehensive oral care
Thorough cleaning without compromise. The brush with the Premium All-in-One head removes up to 20× more plaque, even in hard-to-reach areas. It restores a brighter appearance to your teeth by removing up to 100% more stains in just 2 days. It also helps to improve gum health, for up to 15× healthier gums in just 2 weeks. Discover a whole new feeling of perfectly clean teeth and fresh, healthy gums.
Philips Sonicare 9900 with intelligent sensors
The DiamondClean Prestige 9900 can instantly alert you to incorrect brushing technique. If you apply too much pressure, the light ring at the base of the handle will turn purple, and the toothbrush will alert you with a gentle vibration to reduce the pressure. If you're scrubbing too hard, the light ring will turn amber, and a vibration will guide you towards a gentler motion. Thanks to this instant 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 spots on a 3D map of your mouth and reminds you to pay more attention to these areas. The app notifies you when you've achieved a perfect clean and advises you on how to brush better and more thoroughly. The TouchUp feature guides you back to any missed areas. Brushing reports are saved directly in the app, where you can review them later. All data is automatically synchronised and updated, even when your phone isn't with you during brushing.
Synchronisation and brush head replacement
The brush 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 brush head approximately every 3 months.
The Philips Sonicare 9900 has useful timers
The Smartimer tracks the recommended minimum brushing 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, which is divided into four quadrants. These features ensure your brushing is effective and perfectly timed.
Stylish storage and charging
The battery indicator light on the toothbrush handle will light up to alert you when the battery is low. If the toothbrush starts to run out of power while travelling, use the stylish, compact travel case with USB charging as a charger. The simple design of the case is made from soft-touch vegan leather and provides secure storage for the toothbrush. The elegant puck-shaped charging base also ensures stylish charging.
