The new Sonicare DiamondClean 9900 Prestige uses AI to save your gums — where to buy
TL;DR: The Philips Sonicare Next-Generation DiamondClean 9900 Prestige is live on Amazon at $379.99. This smart brush uses on-device AI to track your pressure 100 times per second and automatically adjusts intensity in real-time to protect your gums.
Your daily dental routine is getting a high-tech makeover. Philips Sonicare is officially dropping its most advanced electric toothbrush yet: the Next-Generation DiamondClean 9900 Prestige.
Starting at a cool $379.99, this luxury electric toothbrush brings high-tech personalization straight to your teeth. Built around on-device AI and the brand’s SenseIQ technology, the handle monitors your brushing technique 100 times every single second.
If you start aggressively scrubbing like you are scouring a dirty skillet, the brush senses the excess pressure and automatically dials back the intensity in real-time to protect your gums. A glowing light ring built into the base gives instant feedback, letting you know whether you are pressing too hard, brushing too softly, or hitting the sweet spot.
Beyond automatic intensity adjustments, the handle functions like a live oral care coach. It connects to a companion app featuring a 12-segment mouth map that tracks where you brush, highlights missed zones, and guides you through a thorough clean. Philips Sonicare claims the internal motor delivers up to 2,000% more plaque removal and improves gum health by 1,500% over six weeks compared to a manual toothbrush.
You can also tailor the experience to your teeth’s specific quirks using eight distinct cleaning modes and three intensity settings. The design matches the hefty price tag, coming in four sleek matte finishes: Silver White, Quartz Black, Satin Mauve, and Storm Blue. Each unit includes a glass charging base and a leather-style travel case that doubles as a charger.
The Philips Sonicare Next-Generation DiamondClean 9900 Prestige is available on Amazon for $379.99. If you are ready to let artificial intelligence take over your morning dental routine, head over to Amazon to pick one up.
