Philips has launched the Sonicare Next-Generation DiamondClean 9900 Prestige, a motion-tracking smart toothbrush now available in Europe and the US with a broader global rollout anticipated in 2027. The device exemplifies a growing trend of adding digital displays and smart features to everyday items, leveraging artificial intelligence to help users improve their brushing technique and dental hygiene.

Priced at $379.99—undercutting the previous model at $429.99 despite its enhanced capabilities—the toothbrush features a touchscreen displaying eight cleaning modes and three intensity levels, along with a "12-segment mouth map" that shows which teeth sections have been effectively cleaned. Its third-generation AI and "SenseIQ" technology are supported by a colour-changing light ring on the base, and the device can automatically adjust vibration intensity to prevent excessive pressure based on the user's brushing technique; this pricing is also considerably less than Dyson's rival offering at $499.
