Dyson CameraJet Buying Guide: Price, Features, Replacement Costs & Where to Buy

The Dyson CameraJet costs $499.99, and you cannot have one until 8 September. Dyson announced it in Paris on 1 September 2026 — a toothbrush with a camera in it that watches for the gaps between your teeth and fires a jet of mouthrinse at them while you brush.

This guide covers what it costs, what it does, what it costs to keep running, and where to buy it in the US. The running-cost section is the one worth reading twice, because one half of the answer does not exist yet.

How much is the Dyson CameraJet?

$499.99 in the US, in two colourways: Ceramic Ultra Blue and Ceramic Pink.

Dyson’s press release rounds the figure to $499; the store page and the one published review both say $499.99. Best Buy lists the release date as 09/08/2026, matching Dyson’s own “will ship September 8th.”

So the launch and the availability are not the same event. If you order today you are pre-ordering.

What’s actually in the box

This is worth checking before you pick a retailer, because the answer is not the same everywhere.

Dyson describes what it sells as the Dyson Dental System: the CameraJet toothbrush, charging dock, travel case, Dyson Toothpaste and Dyson Mouthrinse. Best Buy’s listing describes the box as the toothbrush, two dual-bristle brush heads, refill dock, travel case and a waterproof USB-C to Pogo-pin charging cable — with no toothpaste or mouthrinse named.

Both were read on 2 September and both are quoted as found. Since the consumables are the part with no published US price, it matters whether your retailer includes them.

What it does

The mechanism is genuinely new. A 100k pixel macro lens camera sits below the brush head and analyses 28 images a second. Dyson’s machine-learning system, which it calls Gap Optical Targeting, identifies the gaps between your teeth and — within 100 milliseconds of spotting one — fires a burst of mouthrinse into it.

Three things support that:

• A conical jet instead of a needle jet. Dyson’s fluid dynamicists argue that the needle-shaped jets used by conventional water flossers punch a hole through plaque without removing it. The conical spray is wider and runs at lower pressure.
• An anti-gravity tank. A 12.5ml tank with a diaphragm pump and pressure chamber, so it keeps jetting when the brush is horizontal — which is where you are when cleaning the backs of teeth. Conventional “straw in a cup” designs draw air and fire blanks.
• Variable sonic oscillation. Dyson says conventional sonic bristles stall against the tooth; varying the angle of oscillation keeps them moving.

It is Wi-Fi connected at 2.4GHz, and the camera doubles as an endoscope streaming to the MyDyson app so you can watch your own mouth while you brush.

On development: six years, 661 engineers, 38 patents filed, 16 million lines of code, and a machine-learning system trained on 470,000 dental images. Dyson developed a proxy plaque with the National University of Singapore’s dental faculty so it could iterate without running a clinical trial each time.

One caution on the performance claims. Most of Dyson’s headline numbers compare the CameraJet against a manual toothbrush, which is a low bar for a $499.99 device. The clinical study behind the gum-health claim ran six weeks with 204 participants, against a manual brush. The only claim benchmarked against rival premium electric toothbrushes is that variable sonic oscillation removes up to 69% more plaque in hard-to-reach areas. Best Buy’s listing adds a “13x more effective” figure that does not appear on Dyson’s own product page.

Replacement costs: what it costs to keep

Here is where a buying guide earns its keep, and where the honest answer is uncomfortable.

Brush heads: $29.99, and there is no way around them

Replacement heads are $29.99 for a pack of two, in regular or sensitive. Each is engineered for three months’ use. That is four heads a year, two packs, about $60 a year.

You cannot shop around. Dyson’s own product page says:

The Dyson CameraJet™ electric toothbrush only works properly with a genuine Dyson brush head.

And every head carries an RFID tag that identifies itself to the device, counts how many cleans it has done, and tells the app when to replace it. That is a closed loop by design — no third-party head is going to satisfy it.

As of 2 September, both variants are listed as currently out of stock on Dyson’s US site.

The mouthrinse: the bigger cost, and nobody can price it

The arithmetic on the rinse is straightforward and the conclusion is not.

A bottle is 400ml. A dose is 12.5ml. That is 32 uses per bottle — about 16 days if you brush twice a day. Over a year that is roughly 23 bottles.

Twenty-three bottles a year is a real recurring cost, and it is very likely larger than the brush heads. Dyson has not published a US price for it.

That is not a gap in this guide’s research. Dyson’s US oral-care accessories page and its brush-heads listing page both return an error instead of any product. To be sure that was Dyson and not a browser problem, the same session loaded Dyson’s hair-care accessories page — 98 products, all priced — and its vacuum accessories page, priced with part numbers. The listing system works. The oral-care catalogue is empty.

For scale only: TechRadar’s reviewer quotes £8.49 / AU$15.99 for Dyson toothpaste and mouthrinse. Those are not US prices, and the line is ambiguous about whether it covers one item or both. This guide does not convert them into a dollar figure, because a converted number would read as a US price and there isn’t one.

So there is no total cost of ownership on this page. Brush heads: about $60 a year, known. Mouthrinse: about 23 bottles a year, unpriced. Any five-year figure would be an invention.

Do you have to use Dyson’s own mouthrinse?

Dyson does not say that you do — and the difference between how it talks about the fluid and how it talks about the brush heads is worth noticing.

For brush heads, Dyson says the toothbrush “only works properly with a genuine Dyson brush head.” For the fluid, it says it has “engineered a complete dental system to optimise the performance” of the device, with “a low-foaming mouthrinse formulated for use with the precision jet.”

Those are different claims. One is a compatibility statement; the other is a performance argument.

The performance argument is not empty, though. Dyson’s stated reason for making both the toothpaste and rinse non-foaming — formulated without SLS — is that foam gets in front of the camera and blocks Gap Optical Targeting. Since the camera is the entire reason to buy this device over a $200 competitor, filling it with an ordinary foaming mouthwash would plausibly degrade the one thing you paid for.

What nobody has established so far is whether plain water works acceptably. No source found says it cannot. This guide is not going to assert either way.

Where to buy the Dyson CameraJet in the US

Dyson’s press release names dyson.com, Dyson Demo Stores and “selected retailers”. WWD’s launch report names the retailers, and the Amazon and Best Buy listings were confirmed directly.

All at the same $499.99. On a newly launched product with a fixed price, the thing to compare is not price but return policy and stock date — and whether the consumables are in the box, which as noted above is not consistent.

Is there a privacy issue with a camera in your bathroom?

It’s a fair question to ask about a Wi-Fi-connected camera pointed inside your body, and Dyson has answered it directly.

Dyson’s statement is that the camera is only active during live viewing or auto-jetting, that no images are recorded or stored on the product or in the cloud, and that images remain private to the user. TechRadar’s reviewer wrote that a Wi-Fi camera in the bathroom “does make me feel a little uneasy” and reported that assurance in the same terms.

That is Dyson’s own claim about its own product. It has not been independently audited by anyone as of publication.

How much do Dyson CameraJet brush heads cost?

$29.99 for a pack of two, in either regular or sensitive.

Each head is designed for three months, so a single user needs four a year — two packs, about $60 annually. The heads are RFID-tagged so the device knows how worn yours is and prompts you through the app. Both variants were out of stock on Dyson’s US site on 2 September.

Can you use other brush heads with the Dyson CameraJet?

No. Dyson states that the toothbrush “only works properly with a genuine Dyson brush head”, and each head carries an RFID tag the device reads.

Anyone used to buying generic replacement heads for an Oral-B or Philips brush should price that in: with the CameraJet, the $60 a year is not optional and not competitive.

Is the Dyson CameraJet worth it?

That depends on something you cannot currently find out, which is what the mouthrinse costs.

At $499.99 it is roughly two and a half times a high-end Philips or Oral-B, and it does something none of them do. The single published review — a week with the device, by TechRadar’s Emily Peck — scored it 4/5 on design and 3.5/5 on value, with “premium price tag with refill costs to consider” listed as a con, and noted it can be messy in flossing mode and that the technique takes learning.

The case for buying: nothing else has the camera, the endoscope view is genuinely novel, and if it gets you flossing when you currently don’t, that is a real health outcome.

The case for waiting: it is pre-order only until 8 September, the replacement heads are already out of stock, the app went live a day before launch, and the recurring cost of the fluid is unknown. None of those is a reason it’s a bad device. All of them are reasons that a week from now you will be able to make this decision with better information than exists today.

The bottom line

$499.99, ships 8 September, sold at Dyson, Amazon, Best Buy, Sephora and Costco. Brush heads are $29.99 a pair, need replacing quarterly, and are locked to Dyson by both policy and RFID — call it $60 a year.

The number missing from every version of this story, including this one, is what the mouthrinse costs in the US. A 400ml bottle lasts about 16 days. Dyson hasn’t said what it charges for one, and its own accessories page can’t tell you today.

Prices and availability were read on 2 September 2026, the day after the announcement, and will change. Nothing here is medical or dental advice; talk to your dentist about your own oral care routine.
