Philips DiamondClean 9900 Uses AI to Show Exactly Where You Missed While Brushing

Philips has launched the Sonicare DiamondClean 9900 Prestige, the latest smart electric toothbrush featuring a third-generation AI model. It gives real-time brushing feedback via a glowing ring on its base, while a touchscreen display highlights specific areas of the mouth that were not properly cleaned. The device aims to remove the guesswork from daily dental hygiene.
