# Dyson CameraJet: A £420 Toothbrush With Computer Vision

> Dyson's first toothbrush, the £419.99 CameraJet (launched 1 September 2026), uses a 100,000-pixel camera and an ML model trained on 470,000 dental images to detect interdental gaps and fire mouthwash jets at them within 100ms — the first mainstream appliance to close the sense-decide-actuate loop in your mouth.

**Dyson's first toothbrush is less a grooming gadget than an embedded computer-vision system that happens to clean teeth.** The [Dyson CameraJet](https://www.prnewswire.com/news-releases/dyson-camerajet-the-first-toothbrush-with-a-camera-and-a-jet-to-target-the-gaps-and-remove-plaque-between-your-teeth-302865389.html), launched on 1 September 2026 at £419.99 ($499 in the US), puts a 100,000-pixel macro camera inside the brush head, runs its frames through a machine-learning model trained on 470,000 dental images, and fires a precision jet of mouthwash at every gap it finds — all within about 100 milliseconds of detection. Cameras in toothbrushes have been tried before, and so have brush-flosser combos. What nobody had shipped until now is the closed loop between them.

## What is the Dyson CameraJet?

The CameraJet is an electric toothbrush that brushes, flosses and applies mouthwash in a single three-minute session. A camera embedded in the head watches your teeth as you brush; when it identifies an interdental gap — the sort of space you would normally floss — a nozzle below the bristles fires a burst of Dyson's own "mouthrinse" into it to flush out plaque. The [Telegraph's launch coverage](https://www.telegraph.co.uk/recommended/health-and-fitness/tech-accessories/dyson-camerajet/), based on an early hands-on briefing, describes a 12.5ml tank between head and handle that holds exactly one session's worth of rinse.

It took [six years, 661 engineers and 38 patents](https://wwd.com/beauty-industry-news/products/dyson-camerajet-oral-care-camera-ai-equipped-toothbrush-1239148778/) to get there, including a roughly five-year collaboration with the National University of Singapore's dentistry faculty, which helped Dyson develop a synthetic ["proxy plaque"](https://www.wallpaper.com/tech/dyson-camerajet-toothbrush) material to test cleaning efficacy in the lab. The brush launches in two colourways — Ceramic Ultra Blue and Ceramic Pink — through Dyson Demo Stores and dyson.co.uk. The UK set [bundles the dock, travel case, two brush heads and starter supplies](https://www.techradar.com/health-fitness/oral-health/dyson-camerajet-review) of the toothpaste and mouthrinse; US buyers get the hardware but [buy the consumables separately](https://www.engadget.com/2248230/dyson-camerajet-is-a-500-three-in-one-toothbrush-that-scans-your-maw/).

## How the camera-guided jet actually works

The interesting engineering is in how modest the components are individually, and how tight the loop between them is. The camera is [only 100,000 pixels](https://www.engadget.com/2248230/dyson-camerajet-is-a-500-three-in-one-toothbrush-that-scans-your-maw/) — 0.1 megapixels, laughable by phone standards but exactly right for embedded inference, where resolution you don't need is latency you pay for. Dyson's *Gap Optical Targeting* system analyses [28 images per second](https://www.prnewswire.com/news-releases/dyson-camerajet-the-first-toothbrush-with-a-camera-and-a-jet-to-target-the-gaps-and-remove-plaque-between-your-teeth-302865389.html), firing the jet as soon as a gap crosses the lens. The product as a whole reportedly runs on 16 million lines of code — a reminder that the physical brush is the smallest part of the system.

The fluid side is equally considered. The 12.5ml tank is an "anti-gravity" design — a diaphragm pump and pressure chamber that keep the jet working whether the brush is upright, angled or horizontal. Each burst is a [broad, cone-shaped spray run deliberately at lower pressure](https://tech.yahoo.com/home/article/dysons-first-smart-toothbrush-has-a-camera-a-jet-for-flossing-and-a-500-price-tag-093000275.html) than a typical water flosser, to be gentler on gums and enamel. The dock refills the tank in about three seconds; the brush also charges over USB-C, so the bulky dock can stay at home when you travel.

Two software details stand out. First, the vision system dictates your toothpaste: the CameraJet needs SLS-free paste, because the foam produced by standard sodium-lauryl-sulfate formulas would occlude the camera — a classic case of the sensor's requirements propagating all the way out to the consumables. Dyson conveniently sells its own SLS-free toothpaste and mouthrinse alongside the brush. Second, privacy: Dyson says camera footage is [never recorded or stored](https://www.prnewswire.com/news-releases/dyson-camerajet-the-first-toothbrush-with-a-camera-and-a-jet-to-target-the-gaps-and-remove-plaque-between-your-teeth-302865389.html), on-device or in the cloud — frames are processed live and discarded, though you can watch the feed in the MyDyson app while you brush.

## What dentists make of it

The Telegraph put the launch to general and cosmetic dentist Dr Tilly Houston, whose verdict is a useful counterweight to the spec sheet. The live camera feedback impressed her most — "a brilliant piece of behavioural design", in her words, for the millions of people who currently do nothing between their teeth. Surveys back up how large that group is: [only around a third of British adults](https://www.electricteeth.com/uk/dental-statistics/) clean interdentally on a typical day, and Dyson's own launch material claims nine in ten people don't floss regularly.

Her reservations are worth taking seriously, though:

- **Mouthwash while brushing is normally a "big no no."** Standard [NHS-endorsed guidance](https://www.gov.uk/government/publications/delivering-better-oral-health-an-evidence-based-toolkit-for-prevention/chapter-8-oral-hygiene) is *spit, don't rinse* — rinsing straight after brushing washes away the fluoride your toothpaste just deposited. Dyson's simultaneous rinse jet sits awkwardly against that advice, and the company's counter-evidence so far is a small internal study of 71 participants.
- **The SLS-free requirement is a real switching cost.** Most mainstream toothpastes foam by design; asking people to abandon a paste they've used for decades is a bigger behavioural hurdle than it sounds, even if SLS-free formulas have [legitimate benefits for ulcer-prone mouths](https://pubmed.ncbi.nlm.nih.gov/30839136/).
- **It won't replace interdental brushes for everyone**, particularly people managing gum disease.
- And her bottom line: "we need large scale, independent scientific research to truly assess the impact."

## How it compares to a decade of attempts

The CameraJet's individual ingredients all have prior art — which makes what Dyson actually did here easier to see, not harder.

| Product | Year | Launch price | Approach |
|---|---|---|---|
| [Onvi Prophix](https://petapixel.com/2016/06/04/400-prophix-toothbrush-also-10mp-camera-mouth/) | 2016 | $400 | 10MP camera streams live video — *you* do the aiming |
| [Waterpik Sonic-Fusion](https://www.dentistryiq.com/dentistry/products/hygiene/article/16367927/flossing-toothbrush-introduced-by-waterpik) | 2018 | ~$180 | Sonic brush + water flosser in one handle, no sensing |
| [Colgate Plaqless Pro](https://www.engadget.com/2020-01-05-colgate-plaqless-pro-electric-toothbrush.html) | 2020 | ~$200 (est.) | Optical plaque sensor lights an LED ring; unclear if it ever properly shipped |
| [Soocas Neos](https://www.prnewswire.com/news-releases/soocas-announces-neos-on-kickstarter-a-revolutionary-dual-action-brushing-and-flossing-electric-toothbrush-301826763.html) | 2023 | $230 ($134 early bird) | Brush + built-in water flosser, crowdfunded |
| [Proclaim Custom-Jet](https://www.cnn.com/cnn-underscored/reviews/proclaim-oral-health-system) | 2024 | ~$600 | 60 water jets in a dentist-scanned, 3D-printed mouthpiece |
| [Feno Smartbrush](https://gizmodo.com/this-300-toothbrush-is-the-worst-thing-ive-ever-shoved-in-my-mouth-2000601900) | 2025 | ~$300 | Full-mouth U-brush, 20-second clean, savaged by reviewers |
| **Dyson CameraJet** | 2026 | £419.99 / $499 | Camera → ML model → auto-targeted jet, closed loop |

Read down that table and a pattern emerges. The Prophix could *see* but left the decisions to you. The Sonic-Fusion could *jet* but aimed blindly wherever you pointed it, and the Neos inherited the same blindness five years later. The Plaqless Pro could *sense* but only lit a ring. Proclaim aims its sixty jets precisely — from a static 3D scan taken months earlier in a dentist's chair. And the Feno neither sensed nor aimed, which its reviewers duly noticed. The CameraJet is the first to wire perception to actuation in real time: sense, decide, fire, 28 times a second. That's the same architectural step that separates a backup camera from a car that parks itself — and it's why "first major household brand to do this", as the Telegraph puts it, undersells the engineering a little.

Against the incumbents, the pricing depends on which price you believe. On paper the CameraJet undercuts both flagships: Oral-B's iO Series 10 carries an [£800 RRP in the UK](https://www.techadvisor.com/article/2355622/oral-b-io-series-every-model-compared.html) ($399.99 in the US) and Philips' Sonicare 9900 Prestige lists around £550. On the street it's the other way round — both routinely sell for £250–400, comfortably below the CameraJet's fixed launch price, and [perfectly serviceable electric brushes exist for under £50](https://www.techadvisor.com/article/724959/best-cheap-electric-toothbrush.html). What every tier above that baseline is really selling is sensing and software; Dyson has pushed that logic further than anyone, and priced it accordingly.

## The running costs are the real spec sheet

The £419.99 is only the entry fee. Replacement heads run roughly £25–30 for a pair, RFID-tagged so the brush tracks their wear. The mouthrinse costs about £8.49 for 400ml — and at 12.5ml per session, twice a day, that bottle lasts just over two weeks, or about £16 a month before you've bought the ~£10 SLS-free toothpaste the camera effectively mandates. That's a proper consumables ecosystem, in the finest tradition of razors and inkjet printers, and it's locked in by a *technical* dependency (foam blocks the lens) rather than a mere warranty clause.

## Should you care?

As a first-generation product, the honest answer is probably: watch, don't buy. The Telegraph's own verdict is that it "needs shrinking, for starters", the simultaneous-mouthwash question genuinely contradicts current dental guidance, and Dyson's efficacy claims — [up to 69% more plaque removal in hard-to-reach areas](https://www.prnewswire.com/news-releases/dyson-camerajet-the-first-toothbrush-with-a-camera-and-a-jet-to-target-the-gaps-and-remove-plaque-between-your-teeth-302865389.html) than premium rivals — are lab results awaiting independent replication.

But as a signpost, it's hard to ignore. A mainstream appliance brand just shipped a real-time computer-vision pipeline — camera, ML inference, actuation, app streaming, privacy-by-design — into a wet, foamy, GPU-free environment at a consumer price point, and made the machine-learning model the product's entire reason to exist. Ten years ago that stack lived in research labs. Now it's in a toothbrush, and the most telling detail is the most mundane one: the model's training set, not the motor, is the moat.
