Philips Sonicare is best known for its electric toothbrushes, but the company's newest model adds artificial intelligence to help users brush more effectively.
The Philips Sonicare Next-Generation DiamondClean 9900 Prestige uses on-device AI and SenseIQ technology to monitor brushing habits in real time, according to a community announcement. The toothbrush is designed to adapt to how people brush, provide personalized feedback and help improve cleaning performance over time.
Smart toothbrushes aren't exactly new, but Philips is taking things a step further with a model that can automatically adjust as you brush. Here's what to know about the Philips Sonicare DiamondClean 9900 Prestige and the features that set it apart from a standard electric
toothbrush.

The DiamondClean 9900 Prestige starts at $379.99, making it one of the more expensive electric toothbrushes on the market. Still, its AI-powered coaching, adaptive cleaning technology and premium extras help explain why it sits in the luxury oral-care category.

It uses AI to monitor how you brush
This new toothbrush is powered by Philips Sonicare's SenseIQ Adaptive Intensity technology, which monitors pressure, motion and brushing coverage up to 100 times per second.
When you brush too hard, the toothbrush will automatically reduce intensity to help protect teeth and gums. A three-level light ring also provides real-time pressure feedback, showing whether you're using too little pressure, the right amount or too much.
Even better, the DiamondClean 9900 Prestige pairs with the free Philips Sonicare app, which offers real-time coaching, a dynamic 12-segment mouth map and personalized tips designed to improve brushing technique and coverage over time.
What makes this toothbrush different?
While many electric toothbrushes do offer timers, pressure sensors and/or app connectivity, the DiamondClean 9900 Prestige combines those features with AI-powered personalization that adapts to an individual's brushing habits.
This toothbrush allows you to choose from eight cleaning modes and three intensity levels, while the Premium All-in-One brush head is designed to tackle plaque, stains and gum care without requiring users to switch brush heads. Plus, the toothbrush can remove up to 2,000% more plaque than a manual toothbrush and deliver up to 1,500% healthier gums in Clean mode after six weeks.
Additional features include scrubbing feedback that detects back-and-forth brushing motions, a quieter next-generation motor and technology designed to help maintain consistent cleaning performance throughout the mouth.

Why does this toothbrush cost nearly $400?
The DiamondClean 9900 Prestige is positioned as a luxury oral-care device rather than a basic electric toothbrush.
Along with AI-powered coaching and adaptive cleaning technology, it comes with premium extras including a glass charging base and a travel case that doubles as a charger. The toothbrush also incorporates more sustainable materials, including brush heads made with 70% bio-based plastic, paper-based packaging and a design that improves battery repairability.
I tried it for a week: Was it worth the cost?
I've been using the DiamondClean 9900 Prestige for about a week, and one of the first things I noticed was how clean my teeth felt after each brushing session. The app has been the standout feature for me. It shows me where I'm doing well, highlights areas I may have missed and provides helpful feedback that has made me more aware of my brushing habits. What sounds like a gimmick at first has actually become one of my favorite features, and I find myself checking the app after nearly every brushing session to see how I did.
For me, features like the personalized coaching, real-time pressure feedback and detailed brushing insights help justify the premium price point and set it apart from a standard electric toothbrush.

Does an AI toothbrush replace dental checkups?
No. An AI-powered toothbrush can provide feedback about brushing habits and oral-care routines, but it does not replace professional dental exams or cleanings.
Dentists can identify issues such as cavities, gum disease and other oral-health concerns that may not be detected through at-home brushing tools.
