Dyson just launched a $499 toothbrush that AI-flosses your teeth

Dyson launched a $499 toothbrush with a 100,000-pixel camera that analyzes 28 images per second and aims a mouthwash jet between teeth while the user brushes. It sounds excessive, but it is a useful signal that computer vision is moving into very ordinary health routines where feedback can happen in real time.
Dyson trained an AI on 470,000 dental images and put it inside a toothbrush. With a camera. That flosses for you. In real time.

Q1What did Dyson actually launch?
Dyson's official announcement describes CameraJet as a toothbrush with machine-learning vision that identifies gaps between teeth and triggers a precision jet of mouthrinse while brushing.
Q2How does the camera work?
A 100,000-pixel macro camera analyzes 28 live images each second. Dyson says images are used during live viewing or auto-jetting and are not recorded or stored on the product or in the cloud.
Q3Is the AI doing diagnosis?
No. The core AI task is geometric: detect and track gaps, then aim the jet. The app also maps brushing coverage and gives technique feedback, but Dyson is not positioning it as a substitute for a dentist.
Q4Why charge $499?
Dyson is applying the same premium strategy it used in hair care: custom hardware, sensors, software and a new routine bundled together. The price is far above mainstream electric toothbrushes, so willingness to pay is the real commercial test.
Q5What is the broader signal?
Cheap embedded vision is turning static consumer devices into feedback systems. The question is whether users value that intelligence enough to pay a large hardware premium once the novelty disappears.
