Dyson launched a $499 electric toothbrush on Tuesday that uses a built-in camera and machine learning to spot gaps between teeth and flush them with mouthrinse.
- The CameraJet pairs sonic brushing with an automated mouthrinse jet, selling for $499 in the United States and 419.99 pounds in Britain.
- A 100,000-pixel camera reads 28 images a second and fires within 100 milliseconds of finding a gap between teeth.
- Dyson says the system was trained on 470,000 dental images and keeps no footage on the device or in the cloud.
Founder James Dysonintroduced the brush at an event in Paris. It reached company stores and the Dyson website the same day, priced at $499 in the United States and 419.99 pounds in Britain.
A 100,000-pixel macro camera sits beside the bristles and feeds a system the company calls Gap Optical Targeting.
The software reads 28 images a second, then fires a cone of mouthrinse within 100 milliseconds of finding a gap. Dyson trained that model on 470,000 dental images. A 12.5-milliliter tank of alcohol-free rinse sits under the brush head, and the dock refills it in about three seconds.
Development took six years and involved 661 engineers, 38 patents and 16 million lines of code, according to figures the company listed at the launch. Dyson says laboratory tests showed the brush removed up to 69% more plaque in hard-to-reach areas than leading premium rivals.

Engineer Niamh Turneysaid the team treated poor flossing as a behavioral problem rather than an engineering one. They asked whether people could floss without floss, then folded the answer into a routine most people already follow. James Dyson said the brief was to see the gaps, clear the plaque and improve cleaning during the brushing itself.
Company research cited at the launch found that nine in 10 people floss less often than dentists advise, while the average brushing session lasts about 45 seconds.
Dyson also formulated a non-foaming toothpaste, because foam clouds the lens. Oral-B and Philips already offer app-connected brushes that log coverage, pressure and brushing time. Neither puts a camera inside the mouth.
Reviewers who tested early units questioned the running costs, with replacement heads at 25 pounds for a pack of two. Some also flagged unease about a Wi-Fi camera in a bathroom, though Dyson says the feed runs live only and stores no images on the device or in the cloud.
The premium pricing follows a familiar pattern for the company. Dyson moved into hair care in 2016 with the $399 Supersonic dryer, added the Airwrap styler, and later sold the Zone air-purifying headphones, which lasted only briefly. Each product entered an established category at the top of the price range, and each leaned on engineering claims rather than a lower price.
