Philips has finally put its motion-tracking smart toothbrush into stores, and it is cheaper than the Dyson that started the trend. The Philips Sonicare Next-Generation DiamondClean 9900 Prestige is now available in the US and Europe, with a wider rollout planned for 2027.
The new model costs $379.99, which is less than Dyson’s CameraJet smart toothbrush, priced at $499. The older DiamondClean model remains on sale at a discounted price.
The display that tells you where to brush
The toothbrush comes with a touchscreen that lets you pick from eight cleaning modes and three intensity settings, including gentle options for teeth or gums that are sensitive. The screen shows a “12-segment mouth map,” which changes color to show where you have brushed well and where you need to try again.
The toothbrush tracks your motions to make that map work. It tells you when you are pressing too hard during a clean.
The light at the bottom
The base of the toothbrush has a glowing, color-changing light ring that works with a third-generation AI model and Philips’ “SenseIQ” technology. Together, they warn you if you are pressing too hard while brushing.
If the toothbrush decides you are pressing too hard, it can adjust its own vibration intensity to keep your teeth safe.
What it does not do
The toothbrush does not floss for you. That is a fair trade for the price difference against Dyson.

| US and Europe | Now |
| Global | Expected 2027 |
A display that replaces a mirror
The Next-Generation DiamondClean 9900 joins a growing list of devices with built-in displays that have worked just fine for decades without. The toothbrush’s touchscreen replaces the old method of looking in a mirror and hoping you covered everything.
Why the price matters
Dyson’s CameraJet is the toothbrush that made this category a thing. It cost $499 and some early buyers have had problems with it. The Philips model is cheaper and skips the camera entirely.
What the technology actually does
The toothbrush uses AI and motion tracking to guide your brushing. It knows when you are missing spots and when you are pressing too hard. It tells you both things.
Our verdict on the toothbrush
The toothbrush is cheaper than the Dyson it competes with, and it offers real feedback on how you brush.
The ability to adjust vibration intensity based on your technique is the kind of feature that makes the price feel justified. It is not a gimmick — it is a tool that could actually improve your dental health over time.
The mouth map is the star of the show. Seeing which teeth need more attention is a simple idea, but it is effective. The light ring and the SenseIQ system add polish, though they are secondary to the core experience.
The bigger picture
Smart toothbrushes are becoming common. The Next-Generation DiamondClean 9900 is a strong entry in that field, and its price point gives it a real chance to succeed.
