Dyson unveils CameraJet toothbrush that uses a camera and jet spray to floss while you brush

The CameraJet is Dyson’s attempt to combine brushing, flossing and rinsing in one product. A 100,000-pixel macro lens camera sits just below the brush head and livestreams video to a smartphone over Wi-Fi. An AI system called Gap Optical Targeting analyzes 28 frames per second and fires a cone-shaped blast of mouthwash within 100 milliseconds of detecting a gap. Dyson says the wider, lower-pressure spray removes plaque more gently than conventional water flossers. It is the first electric toothbrush to incorporate a camera into the brush head, according to The Verge.

The machine-learning system was trained on 470,000 dental images and relies on 16 million lines of code, according to Dyson. The camera also works as a dental endoscope in the MyDyson app, letting users inspect their mouths as they brush. Dyson says no images are recorded or stored on the product or in the cloud.

James Dyson said in a statement: “By combining a camera, machine learning, precision fluid dynamics, advanced brushing technologies, connectivity and Wi-Fi, Dyson CameraJet introduces an entirely new way to keep your mouth healthy.”

The toothbrush has a 12.5-milliliter mouthwash reservoir and an “anti-gravity” air-bladder system that Dyson says keeps the pump working in any orientation, even upside down. The included charging dock refills the tank in three seconds. The brush head oscillates nearly 1,000 times per second and uses softer outer bristles along the gumline and stiffer inner bristles for stain removal. Replacement heads carry an RFID tag that alerts the user when a new head is needed after about three months. TechRadar lists a pack of two replacement heads at £25.

Dyson says the cone-shaped spray is the result of years of fluid-dynamics work; Engadget reports that Dyson developed its own proxy plaque through a five-year collaboration with the National University of Singapore’s Faculty of Dentistry. Dyson also plans to sell its own non-foaming toothpaste and a low-foaming mouthwash so the camera can see clearly. The toothbrush works with regular toothpaste and mouthwash, but foam can interfere with the optical targeting.

Pricing varies by outlet: The Verge lists the CameraJet at $499 in the U.S., while TechRadar quotes a U.K. price of £419.99 and converts that to roughly $568, with Australian pricing around A$794. Engadget called it a $500 three-in-one toothbrush.

TechRadar, which tested the CameraJet for a week before launch, said it delivers a deep, thorough clean but requires practice. “Getting the right technique is a bit of a learning curve, but it did leave me with teeth and gums that felt fresh and cleaner each time I used it,” its review said. The Verge wrote that the price is only slightly higher than other premium smart toothbrushes and could be worth it for people who avoid regular flossing.
