Dyson on September 1, 2026 unveiled the CameraJet, a $499 electric toothbrush that uses a built-in camera and an on-device machine-learning system to find gaps between teeth and fire mouthrinse at them while the user brushes. Founder and chief engineer James Dyson presented the device in Paris as the company’s first oral-care product after six years of development.
