Dyson rolls out $499 AI-powered toothbrush with built-in camera
Dyson has expanded into the bathroom appliance sector with the CameraJet, an electric toothbrush that integrates artificial intelligence, a macro lens and an automatic water flosser.
Unveiled Tuesday in Paris, the device carries a $499 retail price and aims to consolidate dental hygiene routines into a single automated step.
The core technology relies on a 100,000-pixel camera that captures 28 frames per second. Operating alongside an algorithm trained on more than 470,000 dental images, the device identifies the specific gaps between teeth where plaque hardens. Once it detects an interdental space, the brush fires a conical jet of liquid within a tenth of a second to flush the area.
Engineering an automated dental routine
Founder James Dyson framed the release as a direct response to poor oral hygiene habits, noting that while consumers understand the value of flossing, they often skip the practice because it requires too much time and effort. The CameraJet eliminates this friction by performing both actions simultaneously. According to the company, laboratory testing showed the device removes up to 69% more plaque in hard-to-reach areas than premium competitors.
To deliver consistent pressure regardless of how the user holds the handle, engineers designed a 12.5-millilitre reservoir with an expanding silicone membrane. This limits the air layer inside the tank, ensuring a steady stream of alcohol-free mouthwash whether the user holds the brush vertically or horizontally. The sonic motor driving the bristles operates at 245 cycles per second and adjusts its oscillation angle dynamically to prevent stalling under heavy pressure.
Developing the hardware required six years of research, involving 661 engineers and generating 38 patents. To keep the camera lens clear during use, Dyson also formulated proprietary non-foaming toothpaste and low-foaming rinses specifically for the hardware.
Privacy safeguards and application limitations
Putting a camera inside a bathroom appliance raises immediate security questions, which the manufacturer attempted to address before launch. The company confirmed that no video or images are stored locally, within the companion application or on cloud servers. A white LED indicator remains illuminated on the handle whenever the lens is active.
Data sent to the MyDyson app translates into a digital map showing exactly which areas were cleaned and which were missed. The software then offers tailored feedback to improve technique. Despite the premium price tag, the application only supports a single user profile per device.
The CameraJet is available for preorder in the US and South Korea. It comes in two finishes: Ceramic Pink and Ceramic Ultra Blue.
