Dyson unveiled the CameraJet on Tuesday in Paris — a $499 electric toothbrush that uses a built-in camera and an AI system to find the gaps between teeth and fire a burst of mouthrinse into them while you brush. Founder and chief engineer James Dyson, who is in his late seventies, presented the device as the company’s first move into dedicated oral care after six years of development, according to the Dyson launch statement distributed via PR Newswire.

The CameraJet is listed for preorder in the United States in Ceramic Ultra Blue and Ceramic Pink. The box includes a refill dock, two regular brush heads, a charging cable, and a travel case. Dyson is selling it through its own site and stores, with U.S. retail partners that, according to The Verge’s coverage, include Amazon, Sephora, Best Buy, and Costco.

“Flossing is an awkward and time-consuming chore. Few of us do it even though we know we should,” Dyson said in the launch statement. “Our research has shown that people consistently miss the areas where plaque forms: the gaps between teeth.” He said the team wanted to solve three problems at once: seeing those gaps, removing plaque, and improving the brush itself.

Dyson’s own usage research, cited in the press release, found that 9 in 10 people do not floss as often as dentists recommend, and that the average brush lasts about 45 seconds, well short of the two-minute guideline from the American Dental Association. The World Health Organization’s oral health fact sheet puts the global stakes higher: nearly 3.7 billion people live with oral disease, the most common health condition tracked in the Global Burden of Disease 2021 dataset. The CameraJet lands inside a broader pattern of sensor-rich personal-care devices that have come to market in recent years, including medical-adjacent consumer products where lab-tested claims outrun large-scale clinical evidence.

The hardware sits in a brush head about the size of a pencil tip. A 100,000-pixel macro lens and a strobing light sit under the bristles. Dyson calls the software Gap Optical Targeting. The system analyzes 28 live images a second and triggers a conical jet of mouthrinse within 100 milliseconds of spotting a gap. The model was trained on 470,000 dental images collected during development, Wired reported, and the product runs on 16 million lines of code, according to Dyson.

That jet is the other half of the pitch. Traditional water flossers often use a thin needle stream. Dyson’s fluid team spent years shaping a wider cone after lab work with a proxy plaque developed in a five-year collaboration with the Faculty of Dentistry at the National University of Singapore. The company says the cone covers more of the gap at lower pressure, which it claims is gentler on gums and enamel. Wired noted that the jet design is the kind of engineering Dyson is known for: more pieces, more precision, more patents than a typical consumer gadget.

The onboard tank holds 12.5 milliliters of alcohol-free mouthrinse. Dyson designed an anti-gravity reservoir with an air bladder and a diaphragm pump so the jet still fires when the handle is tilted or held sideways along the back teeth. The charging dock refills the tank in three seconds and charges the brush between uses. Battery life is listed at up to 10 days, with a full charge in about eight hours. The handle weighs about 228 grams.

The head uses two bristle types. Firmer inner bristles work on surface stains. Softer outer bristles sit along the gumline. Dyson’s variable sonic oscillation changes the angle of the stroke so the bristles keep moving instead of stalling against a tooth. External laboratory tests cited by the company say the CameraJet removes up to 69 percent more plaque than market-leading premium electric toothbrushes in hard-to-reach areas, in brush-only variable mode. That figure comes from a Dyson lab test on Dyson’s proprietary proxy plaque, not from a large multi-site clinical trial against every rival on the shelf — a distinction the press release does not lead with.

Each head carries an RFID tag that tracks how many cleans it has done and flags a replacement, typically every three months. A sensitive head is also in the range. The company says 661 engineers worked on the project and filed 38 patents — a research-and-development spend that fits Dyson’s pattern of over-engineered consumer launches. Steven Ong, Dyson’s Singapore-based head of design engineering, said the compact layout was part of the brief. Dyson told reporters he has used a prototype for about a year and that his hygienist now has less cleanup work to do.

The CameraJet connects over 2.4 GHz Wi-Fi and Bluetooth to the MyDyson app. Users can watch a live endoscope view, run guided cleans, and see coverage maps and session notes. Dyson says the camera turns on only for live viewing or auto-jetting. Images are not stored on the device or in the cloud. Auto-jet and manual jet modes are both available, and brushing intensity can be changed in the app.

There is a catch on paste. Foam blocks the lens. Dyson is preparing an SLS-free, non-foaming toothpaste and a matching low-foam mouthrinse so the camera can keep a clear view. Those formulas are part of what the company is calling a wider Dyson Dental System, with refill subscriptions expected later. Until those bottles ship, the company tells buyers to use a clear, low-foam rinse and an SLS-free paste for best results — and notes that sodium lauryl sulfate is the foaming agent to avoid.

The CameraJet is not the first over-engineered bathroom gadget to ask consumers to pay a premium for sensor-driven insight into a routine they already do badly. A smart toilet sensor that tracks gut health and hydration runs on the same logic: a daily habit, a sensor in an awkward place, an app that turns body output into a chart. Dyson’s first oral-care product sits at the same intersection, but the price sits above it. The CameraJet also continues Dyson’s two-decade push into over-engineered personal electronics with refill subscriptions and an app ecosystem, a category the inventor of the Roomba now occupies from a different angle with a Japanese robot designed for personal-care-style interactions showing where the broader AI-camera-meets-personal-care trend is heading. The premium price tag also fits the broader pattern of luxury consumer electronics asking consumers to pay for design and refill ecosystems rather than raw specs.

The CameraJet’s price sits above flagship Oral-B iO and Philips Sonicare models, which already track time, pressure, and coverage by app, but those brushes do not put a camera in the head or fire rinse into the gaps on their own. Early testers who used review units said the jet is noticeable but not painful, and that the handle needs a slower oval motion than a typical electric brush. How the 69 percent plaque claim holds up in independent clinical work remains an open question — Dyson’s published comparison is a lab test, not a multi-site trial.

U.S. buyers can order now at dyson.com. The U.K. price is £419.99. Singapore listings put the unit at S$699, with in-store sales starting September 2. Australia is listed at A$799 from the same date. Dyson Demo Stores will have units on the floor for people who want to see the head, the dock, and the live camera feed before they spend $499 on a toothbrush.
