It costs $499 and ships this month.*\n\nJames Dyson unveiled the CameraJet in Paris on September 1, 2026. It's an electric toothbrush with a built-in camera, and Dyson is calling it the first of its kind. A 100,000-pixel macro lens sits at the base of the brush head, feeding a machine learning system Dyson calls Gap Optical Targeting. The AI scans your mouth in real time, spots the spaces between teeth where plaque hides, and triggers a burst of mouthrinse to flush them out, all while you're still brushing.\n\nAccording to Dyson's own product materials and a PR Newswire release announcing the launch, the system runs on 16 million lines of code and was trained on a dataset of 470,000 dental images collected during development. That's the part worth sitting with. This isn't a chatbot wrapped around a website. It's computer vision and a machine learning model doing inference on a physical device in your hand, deciding in real time where to point a jet of liquid inside your mouth, with no round trip to a server and no room for a laggy response. Engadget's writeup of the launch pegged the reaction time at roughly 100 milliseconds from detection to jet.\n\nSix years of work sit behind that number. Dyson says 661 of its engineers worked on the CameraJet, the company has filed 38 patents tied to it, and its dental research involved a partnership with the National University of Singapore's Faculty of Dentistry. That's not marketing gloss. It's an unusually long and expensive R&D cycle for what is, on the surface, a toothbrush.\n\n## A Different Bet To The Chatbot Boom\n\nMost consumer AI announcements this year have been about bigger models and bigger context windows. The CameraJet points somewhere else entirely: real-time computer vision plus millisecond-latency physical actuation, packed into a device you hold in one hand and charge on a countertop. Dyson isn't a research lab shipping a demo. It's a legacy hardware company putting edge AI inference into a $499 consumer product and expecting to sell it at scale, the same way it sold vacuums and hair dryers.\n\n[Meta Permanently Disables Cameras on Thousands of Tampered Smart Glasses](https://startupfortune.com/meta-permanently-disables-cameras-on-thousands-of-tampered-smart-glasses/)\n\nMeta has permanently disabled the cameras on an estimated low thousands of Ray-Ban Meta and Oakley Meta glasses after detecting owners tampered with the privacy LED that warns bystanders they're being recorded. The move builds on a July 2026 update and follows Meta VP Alex Himel calling it a 'cat and mouse game' against a small minority of users. - [how to disable tampered smart glasses camera permanently](https://startupfortune.com/meta-permanently-disables-cameras-on-thousands-of-tampered-smart-glasses/) - [meta ray ban glasses privacy led tampering consequences](https://startupfortune.com/meta-permanently-disables-cameras-on-thousands-of-tampered-smart-glasses/)\n\nThat's the part that should interest anyone watching where AI investment goes next. Running inference on-device, fast enough to act on 28 frames a second without lag, is a very different engineering problem than serving a language model from a data centre. It needs low-power chips that can do real work locally, and it needs a dataset nobody else has. That's the moat. Dyson's 470,000-image training set is exactly that kind of asset, the same pattern investors have chased in medical imaging and industrial inspection. Now it's showing up in a bathroom appliance.\n\n## Price, Privacy And What Happens Next\n\nThe device syncs with the MyDyson app for a live endoscopic view of your mouth, tracking which spots you keep missing over time. Dyson says the camera feed is optional. Images processed on the device or in the app are never stored or shared, the company says - a detail worth taking seriously given how squeamish people are about cameras near their faces. Whether that promise holds up under scrutiny is a separate question from whether the engineering works, and it's one privacy researchers will likely test.\n\nAt $499, the CameraJet costs roughly three to four times what a high-end electric toothbrush from Oral-B or Philips typically runs. It's launching first in two finishes, Ceramic Ultra Blue and Ceramic Pink, according to Dyson's product listing. Whether shoppers pay a premium for AI-guided flossing is genuinely an open question. But the technology underneath it - cheap enough edge silicon and a tight enough training set to make split-second decisions on a device this small - is the more interesting story. That's the bet other hardware makers will be watching closely over the next year.\n\n**Also read:** [Tencent Shrinks Its 770-Billion-Parameter Hy4 Model to Run on a Gaming Laptop](https://startupfortune.com/tencent-shrinks-its-770-billion-parameter-hy4-model-to-run-on-a-gaming-laptop/) • [Fei-Fei Li's World Labs Launches Atlas to Build Walkable AI Worlds](https://startupfortune.com/fei-fei-lis-world-labs-launches-atlas-to-build-walkable-ai-worlds/) • [Tesla's Own NHTSA Filing Says Autopilot Was On in a Fatal Texas Crash Police Missed](https://startupfortune.com/teslas-own-nhtsa-filing-says-autopilot-was-on-in-a-fatal-texas-crash-police-missed/)", "url": "https://wpnews.pro/news/dyson-s-499-camerajet-toothbrush-uses-ai-to-aim-a-water-jet-at-your-teeth", "canonical_source": "https://startupfortune.com/dysons-499-camerajet-toothbrush-uses-ai-to-aim-a-water-jet-at-your-teeth/", "published_at": "2026-09-02 10:17:45+00:00", "updated_at": "2026-09-02 10:22:16.320125+00:00", "lang": "en", "topics": ["artificial-intelligence", "computer-vision", "ai-products", "machine-learning"], "entities": ["Dyson", "James Dyson", "CameraJet", "Gap Optical Targeting", "National University of Singapore's Faculty of Dentistry", "MyDyson app"], "alternates": {"html": "https://wpnews.pro/news/dyson-s-499-camerajet-toothbrush-uses-ai-to-aim-a-water-jet-at-your-teeth", "markdown": "https://wpnews.pro/news/dyson-s-499-camerajet-toothbrush-uses-ai-to-aim-a-water-jet-at-your-teeth.md", "text": "https://wpnews.pro/news/dyson-s-499-camerajet-toothbrush-uses-ai-to-aim-a-water-jet-at-your-teeth.txt", "jsonld": "https://wpnews.pro/news/dyson-s-499-camerajet-toothbrush-uses-ai-to-aim-a-water-jet-at-your-teeth.jsonld"}}
