Dyson launched the CameraJet on Sept. 1 in Paris: a $499 electric toothbrush with a camera in the head, an on-device AI model that hunts the gaps between your teeth, and a built-in jet that fires mouthrinse at those gaps while you brush. James Dyson’s line is that this is “an entirely new way to keep your mouth healthy.” The internet’s line, five days later, is that it is a $500 webcam for plaque. Both descriptions are partly true. Here is what the machine actually is, what the claims rest on, and what else you can buy this month that still just brushes teeth.
Futurism framed it as “video surveillance on the inside of your mouth.” That is the joke. The product is real. is it worth the massive price tag? Well… Continued below their promo vid clip – 30 seconds!
What it is
The CameraJet is Dyson’s first oral-care device. It took six years, 661 engineers, and 38 patents, according to the company. Two colors: Ceramic Ultra Blue and Ceramic Pink. In the box: the handle, two regular brush heads, a charging/refill dock, a charging cable, and a travel case. Replacement heads are $29.99 for two. U.S. list price is $499. U.K. list is £419.99. It is on Dyson’s own channels and rolling into Amazon, Sephora, Best Buy, and Costco.
The head carries a 100,000-pixel macro camera — 0.1 megapixels — and a strobing light. That is not a phone camera. It is a targeting sensor. Dyson’s Gap Optical Targeting system analyzes 28 live images per second, was trained on 470,000 dental images collected in development, and runs on what Dyson says is 16 million lines of code. When the model decides the head is over an interdental gap, a conical burst of mouthrinse leaves the jet within 100 milliseconds. The tank holds 12.5 ml. The dock refills it in three seconds.
Dyson calls the jet conical on purpose. Traditional water flossers use a thin, needle-shaped stream. Dyson’s fluid-dynamics team says that profile punched a hole through their test plaque and left the rest stuck. The wider, lower-pressure cone is supposed to sweep more plaque off at once and be gentler on enamel and gums. The brush itself uses “variable sonic oscillation” — the angle of the oscillation changes as you brush so the bristles are less likely to stall against a tooth. Inner bristles are firmer for stain; outer bristles are softer for the gumline. Heads have an RFID tag so the app knows which head is on and when to replace it.
You can watch the feed in the MyDyson app over 2.4 GHz Wi-Fi, with Bluetooth in the pairing chain. The app maps coverage, scores the session, and offers a guided mode. Dyson also sells its own non-foaming, SLS-free toothpaste and a low-foam rinse. The reason is not wellness branding. Foam blinds the camera. Forbes’ David Phelan, after two weeks with one, said Sensodyne Pronamel Gentle Whitening worked as a substitute. He also said the jet is strong enough to kick food out of a contact, the front-tooth pass works better if you smile (messy), and he is still using real floss three times a week.
Dyson’s privacy line, repeated across the launch materials: the camera is on only during live view or auto-jetting; images are not stored on the brush or in the cloud; the feed is private to the phone in that session. That is a company statement. It has not been independently audited. The handle is still a Wi-Fi device in a bathroom. Futurism’s cybersecurity point is the obvious one: if the software is sloppy, the attack surface exists. Dyson has not published a third-party security assessment with the launch kit.
The 69 percent number
The number you will see in every write-up is this: CameraJet “removes up to 69 percent more plaque than market-leading premium electric toothbrushes in hard-to-reach areas.” Read the footnote. That figure is from a laboratory test, in brush-only variable mode, on a synthetic “proxy plaque” Dyson developed in a funded five-year collaboration with the National University of Singapore’s Faculty of Dentistry. It is an engineering benchmark. It is not a two-year gum-disease trial in real mouths against an Oral-B iO plus string floss.
A separate clinical claim — gum-health improvement — used 204 people over six weeks, twice a day, CameraJet in Brush and Auto-jet mode, compared with a manual toothbrush. Manual is the conventional comparator in this category. It is also the weakest one. Nobody who is about to spend $499 is choosing between this and a stick of plastic from the drugstore. They are choosing between this and a $250 Sonicare plus a $60 Waterpik. That study has not been published as a head-to-head against that stack. The Guardian also circulated an “up to 72 percent more plaque” line; Dyson’s own press release uses 69 percent. Use 69, and treat it as a lab number.
WHO still puts global oral disease around 3.7 billion people. Dyson’s own 2017 usage study said 9 in 10 people do not floss as often as they should, and a Journal of Dental Hygiene paper Dyson cites puts average brushing time at about 45 seconds against a two-minute guideline. Those are real problems. A camera is one proposed answer. It is not the only one.
What else is on the market right now
Smart toothbrushes are not new. They have been selling coverage maps and pressure sensors for more than a decade.
Oral-B’s iO Series 9 and 10 sit in the $220–$400 band depending on the week. Magnetic drive, pressure ring, quadrant timer, app coaching that divides the mouth into zones. The iO 10 adds a Wi-Fi dock and live coaching on the base. No camera inside your mouth. Wirecutter still treats the smart layer as optional and keeps pointing ordinary buyers at cheaper oscillating brushes. The Oral-B Pro 1000 — the brush Futurism used as the punchline — is about $40–$50, has a pressure sensor and a two-minute timer, and is ADA-accepted. Ten of those still cost less than one CameraJet.
Philips Sonicare’s 9900 Prestige is the other premium incumbent, typically $250–$380 street. SenseIQ adjusts intensity. The app coaches. Philips has a Next-Gen DiamondClean 9900 Prestige listed for late September 2026 around $380, with an on-handle mouth map and AI guidance — still no endoscope in the bristles.
Feno’s Smartbrush is the other “this is not a toothbrush” product already in the same price neighborhood: $255 on Amazon, $299 for the Founder’s bundle. U-shaped mouthpiece, about 18,000 bristles, a claimed full-mouth pass in roughly 20 seconds, and a handle scanner that feeds the Feno app. CNET’s 2024 hands-on called it a mouthful, literally. Replacement mouthpieces run about $27 every three months. Different bet: brush everything at once instead of aiming a jet.
Then there is the stack most dentists still describe in the chair: a mid-range electric ($40–$80), string floss or interdental brushes ($5), and a countertop or cordless water flosser ($40–$120). Cochrane’s 2019 review of interdental cleaning found that adding something between the teeth to brushing may cut gingivitis and plaque, with low-to-very-low certainty and short trials. Water-flosser studies tend to show better compliance than string, with similar clinical results. Convenience is the actual product Dyson is selling. The camera is how they price it.
What people are saying on X
The viral clip is the demo: a tiny lens, a strobe, a squirt between two model teeth. One widely circulated post called it “peak tech or peak overkill.” Another: “Why are people spending $500 on a new Dyson toothbrush when they can’t even spend $5 for dental floss?” The Telegraph asked its readers the same question about a £420 brush. They were not sold.
Dentists on the platform are not a chorus. A Japanese clinician who bought one posted that the brush feel is in Sonicare territory, the jet is less accurate than the pitch, the camera is a toy after one session, and he would still send patients to a Sonicare. A second dentist-user said the after-clean feel is real and the idea is interesting — and that floss still pulls plaque the jet left. Early hands-on from Forbes matches that split: the auto-jet is the feature, the livestream is a novelty, traditional interdental tools are not retired.
That is the honest read five days after launch. The engineering is not fake. The clinical story is unfinished. The price assumes you will pay Dyson prices for a habit you already skip.
Bottom line
CameraJet is a sonic brush, a low-pressure water flosser, and a 100k-pixel endoscope taped into one $499 handle, with an app that will grade you. Dyson says the pictures never leave your phone. Dyson says the jet finds the gap in a tenth of a second. Dyson says 69 percent more plaque in the hard spots — in its lab, on its proxy, against other electrics in brush-only mode.
If you already floss and own an iO or a 9900, this is a luxury gadget. If you never floss and you will use a jet because a camera does the aiming, it may be the first Dyson product that changes a health behavior instead of a hairdo. The evidence for that second sentence does not exist yet. A $5 box of floss still exists.
