Amsterdam, the Netherlands – Royal Philips (NYSE: PHG, AEX: PHIA), a global leader in oral healthcare, today announced its most advanced, intelligent electric toothbrush ever: the Philips Sonicare Next-Generation DiamondClean 9900 Prestige – a breakthrough in Sonicare's personalized oral care that empowers people 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 well-being [3]. Yet, according to Philips research, more than a third of people (37%) are left guessing if they're brushing well enough between dental visits.
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 people 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 toothbrush [4].
Philips Sonicare is opening a new era of oral care by making the invisible visible.
“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 personalization 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.”
“I was given the Next-Generation Diamond Clean 9900 Prestige and it immediately changed my behavior. 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 personalized biofeedback and a security blanket that will change patient behavior and improve oral health.” Dr. Iain Chapple, Professor of Periodontology, University of Birmingham, UK.

Philips Sonicare ushers in a new era of oral care
The launch of the next-generation Philips Sonicare DiamondClean 9900 Prestige builds on a milestone year for Philips Sonicare. Earlier this year, the brand introduced its new electric toothbrush range 1000-4000 Series and 5000–7000 Series, bringing next-generation sonic technology, refreshed design, more accessible price points and more intuitive brushing experiences to consumers across the portfolio. These series also marked the debut of “Feel the Care,” Sonicare’s refreshed brand direction created to bring the signature ‘Sonicare feeling’ to life through clinically proven performance.
The Philips Sonicare Next-Generation DiamondClean Series 9900 Prestige is part of the new Next-Generation DiamondClean range, including 8000, 8500, 9000 and 9900, and will be available at select retailers across the Europe and the U.S. starting this fall, expanding into other countries later in the year and into 2027.
