Dyson's New $499 Toothbrush Has an AI Camera Inside

Dyson introduced a $499 toothbrush that uses a built-in camera and artificial intelligence to identify gaps between teeth and automatically fire a precision jet of mouthrinse at them while a user brushes, marking the company's expansion beyond its familiar vacuum cleaners and hair care products into oral healthcare, according to Bloomberg's reporting on the launch.

The CameraJet's camera is a 100,000-pixel macro lens capable of capturing 28 images per second while brushing. A machine learning system, trained on 470,000 dental images and running on 16 million lines of code, analyzes those images in real time to locate the specific interdental gaps where plaque first forms and eventually hardens, according to Yahoo Tech's detailed breakdown of the device. Within 100 milliseconds of detecting a gap, the device fires a conical burst of mouth rinse directly at that spot, combining brushing, flossing, and rinsing into a single continuous step rather than three separate routines.

Dyson's plaque removal claims aren't purely marketing language, the company backs them with a specific, multi-year research partnership. To evaluate and optimize how the jet removes deposits, Dyson spent five years working with the National University of Singapore's Faculty of Dentistry to engineer a synthetic stand-in for real plaque, according to Fox Business's reporting on the testing methodology. Under laboratory conditions using that synthetic proxy, Dyson says the device removed nearly 70% more plaque in hard-to-reach areas than premium electric toothbrushes.

Dyson founder and chief engineer James Dyson framed the product's ambition directly: "Flossing is an awkward and time-consuming chore. By combining a camera, machine learning, precision fluid dynamics, advanced brushing technologies, connectivity and WiFi, Dyson CameraJet introduces an entirely new way to keep your mouth healthy."

Given that this is a camera-equipped device users hold inside their own mouths, Dyson was direct about data handling. The company said images captured by the device are not stored or shared, with all processing taking place directly on the device itself rather than uploaded to the cloud, according to Fox Business's reporting.

Dyson's launch fits a genuinely notable, accelerating trend across consumer technology. The product follows a broader push by consumer tech companies to normalize the presence of cameras in devices that didn't traditionally have them, including glasses, headphones, and pendants, according to Bloomberg's reporting, a pattern we've tracked closely in our coverage of Meta, Amazon, and Samsung racing to build always-on AI wearables. Even Dyson's own senior commercial manager, Niamh Turney, positioned this launch as filling a genuine innovation gap, noting prior advances in the oral care category had "largely focused on digital features and brushing specs" without a real technological breakthrough.

Not every signal points toward guaranteed commercial success. Smart toothbrushes, camera-equipped or not, remain a genuinely niche category even after several years on the market, with one study published last year finding more than 85% of participants reported being unfamiliar with the category entirely, according to Yahoo Finance's reporting on the launch's broader market context.

This launch is worth understanding for businesses in consumer electronics, health tech, or personal care evaluating how AI and camera technology are expanding into genuinely unexpected product categories. Dyson's six-year development timeline and rigorous university-backed testing methodology offer a useful template for how established hardware companies are approaching AI integration deliberately, rather than rushing a feature purely to capture market attention.

For businesses in oral care or personal health devices specifically, Dyson's entry into a category historically led by Oral-B and Philips signals genuine confidence that on-device, privacy-preserving AI processing, images analyzed locally rather than uploaded to the cloud, can be a meaningful competitive differentiator as consumers grow more cautious about camera-equipped personal devices.

How much does the Dyson CameraJet toothbrush cost?
The Dyson CameraJet costs $499 and is available now for preorder through Dyson's website and Dyson Demo Stores.

Does the Dyson CameraJet store or share the images it captures?
No. Dyson says images captured by the built-in camera are not stored or shared, with all processing taking place directly on the device rather than being uploaded to the cloud.

How does the CameraJet's AI actually work?
A 100,000-pixel macro camera captures 28 images per second while brushing, and a machine learning system trained on 470,000 dental images analyzes those images in real time to locate gaps between teeth, firing a targeted mouthrinse jet at detected gaps within 100 milliseconds.

Dyson launched the CameraJet, a $499 toothbrush combining a built-in camera, AI trained on 470,000 dental images, and precision mouthrinse jets to automatically target plaque in the gaps between teeth. The company says laboratory testing, developed with the National University of Singapore's Faculty of Dentistry over five years, found the device removed nearly 70% more plaque in hard-to-reach areas than premium electric toothbrushes, with all image processing happening on-device rather than in the cloud. The launch adds to a broader consumer tech trend of embedding cameras and AI into previously unexpected devices, though smart toothbrushes remain a genuinely niche category, with more than 85% of consumers reportedly unfamiliar with it even after years on the market.
