Philips’ new smart toothbrush shows you where you didn’t properly brush
Philips is launching the Sonicare Next-Generation DiamondClean 9900 Prestige, a smart toothbrush featuring AI-driven real-time feedback and a touchscreen interface. The device uses pressure sensors and a mouth-mapping system to guide users toward more effective brushing habits.
Why it matters
This represents the continued integration of AI and sensor technology into everyday personal health devices to improve preventative care.
The latest addition to Philips’ Sonicare line of smart electric toothbrushes could take the guesswork out of your brushing routine. The Next-Generation DiamondClean 9900 Prestige uses a third-generation AI model to provide real-time feedback on how you’re brushing through a glowing ring on its base, while a touchscreen highlights areas of your mouth that may need more attention when you think you’re done.
The Sonicare Next-Generation DiamondClean 9900 Prestige is expected to launch in Europe and the US this fall, with a wider global rollout coming in 2027. Pricing hasn’t been announced, but previous versions sell for $430, and you can expect this new one to be even more expensive.
