Philips’ New Smart Toothbrush Uses AI to Reveal Missed Spots
Philips has unveiled its Sonicare Next-Generation DiamondClean 9900 Prestige, an AI-powered smart toothbrush offering real-time feedback and a touchscreen mouth map to show users overlooked areas. It also features adaptive pressure sensors and multiple cleaning modes. The device is set to launch in Europe and the US this fall.

Philips is once again raising the bar in personal oral hygiene with the introduction of its latest smart electric toothbrush, the Sonicare Next-Generation DiamondClean 9900 Prestige. Announced today, this advanced device leverages a sophisticated third-generation AI model to provide unparalleled real-time feedback, empowering users to pinpoint and address areas of their mouth that may have been overlooked during brushing. This innovation promises to transform daily dental routines by offering data-driven guidance directly from the toothbrush itself.
Introducing the Next-Generation Oral Care
The new DiamondClean 9900 Prestige marks a significant leap forward in Philips' renowned Sonicare line. Unlike previous iterations, this model is designed to actively educate and improve brushing habits through its integrated artificial intelligence. The primary goal is to eliminate the guesswork inherent in manual brushing, ensuring a more comprehensive and effective clean every time.
AI-Powered Guidance and Real-Time Feedback
At the heart of the 9900 Prestige's intelligence is its third-generation AI, which meticulously tracks the toothbrush's movements throughout the mouth. This AI model processes brushing data in real-time, translating it into actionable insights for the user. A prominent glowing ring located at the base of the brush serves as an immediate visual indicator; its color changes dynamically to alert users when they are applying too much pressure, a common cause of gum recession and enamel wear. This intuitive feedback mechanism is designed to gently encourage a lighter, more appropriate brushing technique.
The Interactive Touchscreen Experience
Complementing the AI feedback is an intuitive touchscreen interface integrated directly into the toothbrush handle. This display isn't just for selecting one of the eight available cleaning modes—which include specialized options like "gum health," "max clean," and "sensitive"—it also serves as a crucial diagnostic tool. After a brushing session, the screen presents what Philips terms a "mouth map." This visual representation divides the user's teeth and gums into 12 distinct segments.
The true innovation here lies in how the mouth map leverages the AI's tracking data. Areas identified by the toothbrush as having received insufficient attention during the initial pass will glow orange on the touchscreen. This precise highlighting ensures that users know exactly which specific spots require a "do-over," enabling them to target their re-brushing efforts with surgical precision. This personalized post-brush analysis is a game-changer for achieving consistent, thorough oral hygiene.
Advanced Protection for Gums and Teeth
Beyond guiding optimal technique, the Sonicare Next-Generation DiamondClean 9900 Prestige also prioritizes dental safety. In addition to the visual pressure feedback from the glowing ring, the toothbrush incorporates advanced pressure sensors. These sensors don't just alert the user; they actively adjust the brush's intensity when excessive force is detected. This automatic moderation ensures that the sonic bristles go easier on gums and teeth, minimizing the risk of damage while still providing an effective clean.
Availability and Market Positioning
Consumers in Europe and the United States can anticipate the launch of the DiamondClean 9900 Prestige this fall, with a wider global rollout slated for 2027. This phased release strategy underscores Philips' ambition to establish a new benchmark in connected oral healthcare worldwide. While official pricing details are yet to be revealed, Philips' previous top-tier smart toothbrushes typically retailed around $430. Given the significant advancements in AI and interactive features, prospective buyers should expect the Next-Generation DiamondClean 9900 Prestige to come with an even higher premium, positioning it as a luxury health gadget for discerning users.
The Future of Smart Oral Hygiene
This latest offering from Philips reinforces the growing trend of integrating artificial intelligence and smart connectivity into personal care devices. The DiamondClean 9900 Prestige moves beyond simple timers and basic pressure sensors, offering a truly interactive and adaptive brushing experience. By providing detailed, personalized feedback and active protection, Philips aims to empower individuals to achieve professional-level oral care at home, potentially reducing trips to the dentist for preventable issues. This evolution signals a future where everyday health routines are increasingly informed and optimized by intelligent technology.
