Dyson made a camera-equipped toothbrush that flosses for you
Developing story first seen 4 hours ago
Dyson has launched the CameraJet, a $499 electric toothbrush that becomes the first to build a camera into the brush head, letting users livestream footage of the inside of their mouth via Wi-Fi while an AI feature called Gap Optical Targeting fires mouthwash into gaps between teeth as they brush, effectively flossing automatically. It is on sale now in ceramic blue or ceramic pink, positioning it as a premium option for people who struggle to floss regularly, at a price only slightly above rival smart toothbrushes that lack the camera-and-spray system.
The 100,000-pixel camera, paired with a strobing light, analyses 28 images per second without storing or uploading them, and triggers a cone-shaped mouthwash blast within 100 milliseconds of detecting a gap, using a wider spray than typical water flossers for a gentler clean. The brush head oscillates nearly 1,000 times a second with a varying angle, combines softer outer bristles with stiffer inner ones for stain removal, and uses RFID-tagged heads that need replacing roughly every three months. Its 12.5ml mouthwash reservoir, kept pressurised by an internal air bladder so it works upside down, can be refilled in three seconds by the charging dock, and Dyson plans to sell matching non-foaming toothpaste and low-foaming mouthwash to keep the camera's view clear.

Dyson, the British engineering firm best known for vacuum cleaners, hairdryers and fans, has moved into dental care with an electric toothbrush called the CameraJet. It builds a tiny camera into the brush head, a first for the category, so that a paired app can show a live view inside the user's mouth while brushing.
The toothbrush's main selling point is automated flossing. An AI system called Gap Optical Targeting uses the camera to spot gaps between teeth as they are brushed and fires a precise jet of mouthwash into them, aiming to clean areas that manual flossing often misses or that some people find difficult to do properly.
The device matters because flossing is a common weak point in people's dental routines, and Dyson is betting that combining monitoring technology with automation can make it easier. It also signals the company extending its approach of adding sensors and data feedback, already used in products like its air purifiers, into personal care and health-adjacent devices.
Full account
Dyson has moved from hairdryers and vacuum cleaners into dentistry, unveiling the CameraJet, an electric toothbrush that combines a miniature camera with an automated water-flossing jet. Priced at $499 and sold in ceramic blue or ceramic pink, the device is being marketed as the first toothbrush of its kind to build a camera directly into the brush head, allowing it to both flush debris from between teeth as you brush and stream live footage of your mouth to a smartphone over Wi-Fi.
At the core of the design is a system Dyson calls Gap Optical Targeting, in which a small camera mounted just behind the bristles continuously scans the mouth, reportedly capturing around 28 frames a second, to spot gaps between teeth. Reporting on the camera's technical make-up varied: one account described a 100,000-pixel sensor paired with a strobing light to keep images stable, while another characterised it as a macro-lens endoscope camera driven by machine-learning software that Dyson says was trained on some 470,000 dental images gathered over six years of development. Whichever description is more precise, both agree that once a gap is identified, the brush fires a cone-shaped burst of mouth rinse into it within about a tenth of a second, effectively flossing automatically while the user brushes.
Dyson argues that this wider, conical spray clears plaque more effectively and with less force than the narrow, needle-like jets used in conventional water flossers, making it gentler on gums and enamel, though this is a claim from the company rather than an independently verified finding. To support the plaque-removal claims without repeated clinical trials, Dyson says it worked with the National University of Singapore's dental faculty to develop a synthetic plaque substitute for lab testing. Beneath the brush sits a small reservoir, said to hold around 12.5 millilitres of alcohol-free rinse, which is pushed through the system by an internal pump designed to keep working even if the brush is held upside down; accounts differed on the exact mechanism, with one describing an inflatable air bladder inside the tank and another pointing to a diaphragm-and-pressure-chamber pump, though both were presented as solutions to the same tilt problem. A companion charging dock tops up the rinse tank in a matter of seconds and doubles as a stand for the brush, and a travel case is included.
Beyond the flossing function, the CameraJet is still a sonic electric toothbrush at heart, oscillating close to a thousand times a second with a continually varying angle intended to improve cleaning across the tooth surface. Its replaceable head mixes softer outer bristles for the gumline with firmer inner bristles aimed at tackling stains, and a gentler head variant is said to be available for sensitive teeth and gums. Each head carries an RFID tag that logs how much it has been used, prompting a replacement roughly every three months. Dyson positions the price as only a modest step up from other high-end smart toothbrushes that lack a built-in camera and irrigation system, framing the CameraJet as a premium option for people who consistently struggle to floss by hand.
Where outlets differ
The Verge focuses on camera hardware specifics (a 100,000-pixel sensor with a strobing light) and states images are analysed on-device without cloud storage, while the other outlet instead emphasises the camera as a macro-lens 'endoscope' driven by a machine-learning model trained on 470,000 images collected over six years of R&D.
The two accounts describe the pump mechanism differently — one details an inflating air bladder inside the tank, the other a diaphragm pump and pressure chamber — though both are explaining the same tilt-proof design goal.
One outlet situates the CameraJet in context of Dyson's only prior hybrid device, the short-lived Dyson Zone air-purifying headphones, framing this launch as a more practical pairing of technologies, a comparison the other source omits entirely.
Only one source mentions the National University of Singapore dental-faculty partnership used to create synthetic plaque for testing, the exact rinse tank capacity (12.5ml), the three-second dock refill time, and the existence of a softer brush head for sensitive users.
The Verge places more emphasis on pricing context, noting the CameraJet costs only slightly more than rival premium smart toothbrushes without its camera-and-spray combination.
