Philips Sonicare DiamondClean 9900 Prestige: AI Toothbrush Tracks Missed Spots

Philips has introduced the latest addition to its Sonicare line of smart electric toothbrushes, the Next-Generation DiamondClean 9900 Prestige. This model leverages a third-generation AI model to deliver real-time feedback during brushing via a glowing ring on its base. After brushing, a touchscreen highlights areas of the mouth that may need more attention. The device is expected to launch in Europe and the US this fall, with a global rollout in 2027. Pricing has not been announced, but previous versions have sold for around $430.
