Philips smart toothbrush uses AI to improve brushing technique

Philips has introduced its next-generation smart toothbrush, the Sonicare DiamondClean 9900 Prestige. The device reportedly utilizes artificial intelligence (AI) and motion-tracking technology to analyze a user's brushing technique and provide feedback for improvement.

Initially announced in July, the toothbrush's availability is now expanding to Europe and the United States. A broader global rollout is anticipated by 2027. While the previous DiamondClean iteration remains available at a discounted price, the new "Next-Gen DiamondClean" version is launching for $379.99, a reduction from its predecessor's original price despite its added capabilities.

The Philips smart toothbrush enters a competitive market of intelligent oral care devices. It is priced lower than alternatives such as Dyson's $499 CameraJet, which has reportedly encountered some issues with early adopters. The DiamondClean 9900 Prestige joins a growing trend of devices incorporating built-in displays aimed at enhancing consumer health behaviors through technology.

Philips has not detailed the specific AI functionalities or data handling processes. However, the company's investment in smart home appliances and personal health monitoring is evident.
