Dyson unveils $499 CameraJet toothbrush with built-in camera and automated flosser
The handheld device uses a 100,000-pixel macro camera and machine learning to detect gaps between teeth and fire cone-shaped bursts of mouthwash within 100 milliseconds.
Launch and pricing details
Dyson founder and chief engineer James Dyson unveiled the CameraJet electric toothbrush in Paris on Tuesday, 1 September 2026. The device combines mechanical brushing with automated liquid flossing in a single cordless handheld unit. Retail pricing is set at $499 in the United States, £419.99 in the United Kingdom, and 794 Australian dollars. The complete launch package includes the toothbrush, a specialized charging dock, a travel case, Dyson Toothpaste, and Dyson Mouthrinse. Available immediately in ceramic blue and ceramic pink finishes, the release marks Dyson's entrance into the dental hygiene sector, following earlier consumer hardware expansions into stick vacuums, hair care appliances, and the Dyson Zone air-purifying headphones.
- Dyson spends six years developing the device, training algorithms on 470,000 dental images and creating proxy plaque with NUS.
- James Dyson unveils the CameraJet in Paris, launching the $499 device in ceramic blue and ceramic pink.
- Embedded RFID tags in replaceable brush heads trigger replacement notifications based on usage frequency.
Optical targeting and computer vision
Mounted directly beneath the brush head is an endoscope-style, 100,000-pixel (0.1-megapixel) macro-lens camera equipped with an integrated strobing light. The onboard Gap Optical Targeting system captures and processes 28 live video frames per second to recognize interdental gaps in real time. The computer vision architecture relies on 16 million lines of code and a machine learning model trained on 470,000 dental images gathered across six years of product development. Once the camera identifies an interdental opening, the mechanism fires a targeted burst of mouthwash within 100 milliseconds. To calibrate cleaning performance in laboratory settings without continuous clinical trials, Dyson developed synthetic proxy plaque in partnership with the National University of Singapore's Faculty of Dentistry.
Fluid mechanics and reservoir design
Unlike conventional standalone water flossers that rely on narrow needle-style water jets, the CameraJet discharges a wide conical stream of fluid. Dyson designed the cone-shaped jet to clear plaque across a broader surface area while operating under reduced pressure, aiming to protect sensitive gum tissue and tooth enamel. Liquid feeds from an internal 12.5-milliliter (0.42 fluid ounces, or roughly two and a half teaspoons) anti-gravity tank located around the neck of the brush handle. An internal air bladder expands gradually as liquid is consumed, eliminating air pockets and stabilizing fluid pressure during operation. A diaphragm pump and pressure chamber allow continuous, controlled spraying at any angle, including upside down. When seated in the powered docking station, the internal tank recharges and refills automatically within three seconds.
Brush head mechanics and app connectivity
The replaceable brush head utilizes softer outer bristles for cleaning along the gumline alongside stiffer central bristles intended to scrub away tooth stains. The head oscillates nearly 1,000 times per second, continuously shifting oscillation angles during active brushing sessions. An integrated RFID chip tracks usage frequency and alerts users when the brush head requires replacement at three-month intervals. The device connects over Wi-Fi to the MyDyson mobile application, streaming low-latency video to provide real-time visibility inside the mouth during live viewing or auto-jetting modes. The companion app delivers personalized brushing feedback, technique tutorials, and intensity adjustments, while Dyson states that no oral imagery is recorded or stored on the physical device or in cloud storage.
