Philips Sonicare Next-Generation DiamondClean 9900 Prestige lets patients leave the guesswork behind, offering real-time guidance via light ring, on-device mouth map and smart pressure sensing to deliver 20x1 more plaque removal and 15×2 healthier gums vs manual brushing
Royal Philips has announced its most advanced, intelligent electric toothbrush ever: the Philips Sonicare Next-Generation DiamondClean 9900 Prestige – a breakthrough in Sonicare’s personalised oral care that empowers patients to see how well they’re brushing in real-time.
From heart disease and diabetes to Alzheimer’s and pregnancy outcomes, studies have shown that having a healthy mouth may be integral to overall wellbeing3. Yet more than a third of people (37%) are left guessing if they’re brushing well enough between dental visits, creating an important opportunity for dental professionals to support patients with more personalised home-care guidance.
Building on more than three decades of innovation from the No.1 sonic toothbrush brand recommended by dental professionals worldwide, the Philips Sonicare Next-Generation DiamondClean 9900 Prestige is designed to help patients brush with greater confidence. It combines on-device AI guidance with a powerful yet gentle clean, removing up to 20x more plaque than a manual toothbrush4.
Professor Dr. Iain Chapple commented: “I was given the Next-Generation DiamondClean 9900 to try out and it immediately changed my behaviour. I thought I had a meticulous cleaning regime but checked the mouth map on the handle and had to go back to my outer lower anterior sextant. The next morning, I made sure I rose to the challenge and got a ‘complete clean’. I love the feedback screen and check it every time. It is a game changer in personalised biofeedback and a security blanket that will change patient behaviour and improve oral health.
“Philips Sonicare is opening a new era of oral care by making the invisible visible,” said Francesco Grillo, Philips Global Business Unit Leader – Oral Healthcare. “For decades, people have been told how to brush better, yet most never truly knew how well they were brushing. With our Next-Generation DiamondClean 9900 Prestige, we fundamentally reimagined the brushing experience by combining advanced sensing, real-time guidance and AI-powered personalisation directly within the toothbrush itself. The result is a simpler, more intuitive and more effective way to help people build healthier habits and achieve better oral health outcomes every day.”
The Philips Sonicare Next-Generation DiamondClean 9900 Prestige transforms brushing forever…
Through personalised brushing guidance that helps patients improve their daily oral care.
- Complete care is now 100% visible: The 9900 Prestige uses the brand’s third-generation AI and machine learning model, leveraging spatially aware guidance, to instantly display how well patients are bushing during a session with its new light ring guidance system for a real-time view on coverage, pressure or scrubbing.
- No more guessing, with on-device Mouth Map: Smart Coverage Feedback closely follows a patient’s brushing to help them clean thoroughly. The 12-segment Sonicare Mouth Map on the toothbrush’s display lets them know if they have missed spots while brushing and need a touch-up, or even better, confirms when they have achieved a complete clean. Achieve the perfect pressure, protecting patient’s teeth and gums: Philips SenseIQ smart pressure sensors automatically adapt intensity if patients press too hard.
- Personalise patients’ oral care: Easily swipe to select from 8 modes, 3 intensities and the type of instant feedback communicated via the light ring.
Through a superior brushing experience5 that elevates daily oral health
- Remove plaque deep between teeth and along the gumline: Sonicare Fluid Action pulses fluid deeply in-between teeth and along the gumline to support the bristles to remove plaque.
- Experience a quieter6, gentle clean everywhere: Powered by Next-Generation Sonicare drivetrain previously introduced in Sonicare 5000-7000 series last year, which introduced a quieter motor while providing a gentle-yet-effective clean, even in hard-to-reach areas.
- Designed with the planet in mind: Newly designed encapsulation for battery replacement and repairability and comes in paper-based packaging. Perfectly complemented by Sonicare’s range of brush heads made with 70% bio-based plastic7.
- Elevate the patient experience: As stylish as it is smart, the 9900 Prestige comes in 3 premium colours (storm blue, quartz black, silver white). It also has a sleek, rechargeable travel case and luxury charging glass.
