The CameraJet’s tiny camera captures 28 photos per second. An AI system trained on 470,000 dental images finds gaps between teeth and directs a small rinse stream there during brushing.

It can also stream a live view of the mouth to the MyDyson app, showing cleaning coverage and close-up images of the teeth.

Dyson says development took 6 years and involved 661 engineers. The $499.99 device combines an electric toothbrush, oral irrigator, and camera.
