Dyson put a camera and AI inside an electric toothbrush

Dyson just turned brushing your teeth into a full computing stack.

The company unveiled the CameraJet in Paris, a $499 electric toothbrush packed with Wi-Fi, an optical macro camera, and machine learning designed to spot interdental gaps and blast them with mouthrinse while you brush.

A camera in your mouth

Most people brush for 45 seconds instead of the recommended two minutes, and nine in ten skip flossing entirely. Dyson’s fix is to combine brushing, liquid flossing, and mouthwash into a single motion.

The CameraJet features a tiny 100k-pixel macro lens camera scanning 28 frames per second. Powered by an algorithm called Gap Optical Targeting, the brush detects, tracks, and predicts the gaps between your teeth in real time, triggering a conical spray of mouthrinse within 100 milliseconds of spotting an opening.

Dyson spent six years developing the system with 661 engineers, training the model on 470,000 dental images across 16 million lines of code. It partnered with the National University of Singapore's Faculty of Dentistry to synthesize proxy plaque, ditching conventional needle jets for a wider, low-pressure conical spray designed to sweep plaque without tearing up gums.

Inside the handle sits a 12.5ml anti-gravity reservoir with a diaphragm pump that fires evenly even when held upside down. A specialized dock refills the tank in three seconds flat while charging the device.

The no-foam ecosystem

There is a catch: optical cameras cannot see through dense toothpaste suds. To solve this, Dyson created proprietary non-foaming toothpaste formulated without sodium lauryl sulfate, alongside low-foaming mouthrinse in Ginger Mint and Spearmint.

The brush heads feature dual bristles, sonic dampening, and embedded RFID tags to count clean cycles. Users can livestream the endoscope feed to the MyDyson app to watch missed spots, though Dyson stresses that video stays local and no images are stored on device or in the cloud.

Why it matters

Dyson has always excelled at taking mundane household chores and packaging them into high-margin, hyper-engineered luxury status symbols. For users who chronically neglect flossing, the promise of doing everything automatically in one two-minute sweep sounds genuinely appealing.

However, we think the razor-and-blades lock-in here is aggressive. Dropping $499 upfront is already steep, but requiring proprietary, non-foaming toothpaste just so the camera lens stays clear turns your oral routine into a walled garden.

For the broader health-tech industry, it raises the stakes well beyond oscillating bristle speeds. Competitors like Philips Sonicare and Oral-B will soon have to decide whether consumers actually want optical telemetry in their bathrooms.

Still, engineering an everyday tool with 16 million lines of code, an endoscope, and liquid micro-jets introduces plenty of points of failure in a humid environment. It looks brilliant on paper, but waiting to see how the hardware holds up is probably the smarter move.
