Philips is releasing its Sonicare Next-Generation DiamondClean 9900 Prestige smart toothbrush, now available in Europe and the US. The product, priced around $380, features AI-based motion tracking intended to guide brushing, with claims focused on improving gum care.
The Verge notes the model was first announced in July and had an expected limited launch before expanding. It also says a broader global rollout is planned for 2027, while the prior generation DiamondClean remains available at a discounted price. Mashable highlights the toothbrush’s availability on Amazon and provides an overview of the key features associated with its AI approach.
Across the outlets, the emphasis differs: Mashable centers on where and when to buy and the stated price, while The Verge focuses on the timeline—from initial announcement to regional availability—and the transition from the previous model. Both describe the 9900 Prestige as a next-generation, AI-enabled Sonicare brush that uses motion tracking to support better brushing habits.
