Dyson CameraJet targets tooth gaps with a camera, but still takes practice

A toothbrush that decides when to fire a mouthrinse jet is a more interesting proposition than a toothbrush that merely counts brushstrokes. Dyson's CameraJet, announced on September 1, 2026, uses a camera to locate the spaces between teeth and trigger liquid cleaning. Now that reviewers have lived with it, the contrast between that clever mechanism and bathroom practicality is worth revisiting.

The basic combination is not new. Waterpik's Sonic-Fusion already combined brushing and water flossing in one device in 2018. CameraJet's meaningful distinction is therefore not putting two routines in one handle. It connects visual recognition to the decision to release a jet.

Dyson says its 100,000-pixel camera processes 28 frames per second and can trigger a burst within 100 milliseconds of spotting a gap. Think of a motion-activated light rather than a lamp left permanently on: a sensor decides when to act. Here, the trigger is a tiny space between teeth, encountered as the user moves the brush.

That division of labor still leaves the human with a learning curve. In her prelaunch week-long test, TechRadar's Emily Peck found that jets did not always fire when she expected. Keeping her mouth insufficiently closed also sent spray onto the mirror. She described a fresher feeling but was not ready to abandon dental tape. A reviewer's sensation of cleanliness is not a clinical finding that one device can replace every other cleaning method.

A longer trial highlighted different compromises. Writing on October 16 after a month of use, T3's Lizzie Wilmot reported no functional problems with her unit. But she found the powered dock bulky, refilling potentially messy, and the inability to combine live camera viewing with guided cleaning frustrating. These are ordinary domestic details, yet they determine whether an elaborate appliance becomes a lasting habit or another object beside the sink.

The reviews listed a US price of $499.99 and $29.99 for two replacement heads. For a prospective user, the ongoing expense belongs in the same calculation as the initial hardware. CameraJet is an instructive consumer invention because its automation has a specific job: identifying a location and timing an action. Whether that job is performed conveniently enough every day matters more than the presence of a camera or an AI label. It is an unusual engineering approach, not a reason to infer superior long-term dental outcomes from specifications alone.
