The new Sonicare DiamondClean 9900 Prestige uses AI to save your gums — where to buy

The Philips Sonicare Next-Generation DiamondClean 9900 Prestige electric toothbrush is now available on Amazon for $379.99. This premium device utilizes advanced artificial intelligence technology to enhance your dental hygiene routine.

At the heart of this luxury brush is on-device AI and Philips' SenseIQ technology. As you brush, the handle monitors your technique 100 times per second. If you apply too much pressure - like scrubbing a tough pan - the brush automatically reduces its intensity to protect your gums. An illuminated ring in the base provides real-time feedback, letting you know if you're brushing too hard, too soft, or just right.

Beyond this smart pressure management, the device functions as a personal oral care coach. It connects to a companion app with a 12-segment mouth map that tracks your brushing pattern, highlights neglected areas, and guides you through a comprehensive clean. The brush offers eight cleaning modes and three intensity settings to suit your unique dental needs.

The Sonicare 9900 Prestige boasts up to 2,000% more plaque removal and a 1,500% improvement in gum health over six weeks compared to a manual brush. The design is sleek and matches the price tag, available in four matte finishes: Silver White, Quartz Black, Satin Mauve, and Storm Blue. It comes with a glass charging base and a leather-style travel case that also doubles as its charger.
