Dyson's $499 Smart Toothbrush Combines Live Mouth Camera with AI-Guided Flossing

Dyson has entered the oral care market with an unconventional device: the CameraJet, a $499 electric toothbrush equipped with a built-in camera that livestreams your mouth to your smartphone while simultaneously spraying mouthwash to clean between your teeth. The gadget launches today in ceramic blue and ceramic pink finishes.

How It Works#

The toothbrush contains a 100,000-pixel camera positioned just below the brush head, paired with a strobing light and AI-powered gap detection. The system analyzes 28 live camera frames per second to identify spaces between teeth, then fires a cone-shaped mouthwash spray within 100 milliseconds—a process Dyson terms "Gap Optical Targeting." Notably, the AI processing happens entirely on-device with no cloud transmission or image storage.

Dyson engineered the spray to be gentler than traditional water flossers by using a wider blast pattern that removes plaque effectively while applying less pressure to enamel and gums.

Engineering Details#

The brush head oscillates approximately 1,000 times per second while constantly varying the angle of oscillation to maximize cleaning power. It combines softer outer bristles for gum-line safety with stiffer inner bristles designed to tackle surface stains.

To deliver consistent pressure regardless of orientation—even when held upside down—the mouthwash reservoir contains an air bladder that slowly inflates to maintain pressure and eliminate air pockets. A sophisticated docking station recharges the toothbrush and refills its 12.5ml reservoir in just three seconds.

Compatibility and Customization#

While the CameraJet works with standard toothpaste and mouthwash, Dyson is developing custom formulations: a non-foaming toothpaste and low-foaming mouthwash designed to give the camera clearer visibility inside your mouth. Replacement brush heads include RFID tags that track usage and prompt replacement every three months, though pricing for replacements hasn't been disclosed.

At $499, the CameraJet costs only marginally more than other premium smart toothbrushes without its camera-spray functionality, positioning it as a potential solution for those struggling to maintain regular flossing habits.
