How the camera and the jet work

Dyson calls the system Gap Optical Targeting. A macro lens sits in the neck of the brush head, and it reads 28 live images every second. A machine learning model, trained on 470,000 dental images, decides which of those frames shows an interdental gap. Within 100 milliseconds of seeing one, the brush jets.

The camera and its light strobe at 257Hz, deliberately out of step with the movement of the brush head. That keeps the picture from smearing while the thing holding the camera is oscillating.

The jet itself is a broad cone rather than the needle a water flosser uses. It also runs at lower pressure. So Dyson's argument is that a cone covers the whole gap while staying gentler on gums and enamel. Dyson tested that against a proxy plaque of its own. It came out of a five-year funded collaboration with the National University of Singapore's Faculty of Dentistry.

Feeding the jet is what Dyson calls an anti-gravity tank, holding 12.5ml. A normal flosser draws liquid up a tube, so tilting it pulls in air and the jet stutters. This one uses a diaphragm pump and a pressure chamber instead. That is meant to keep the bursts identical whether the brush is upright, angled or horizontal.

A camera in your mouth, and what happens to the pictures

The brush connects over Wi-Fi at 2.4GHz and Bluetooth. In the MyDyson app you can watch the footage live as you brush. The app also handles guided cleaning, coverage mapping and feedback afterwards.

On the obvious worry, though, Dyson's position is specific. The camera runs only during live viewing or auto-jetting. Dyson also says it keeps no images, either on the product or in the cloud. They stay private to the user. That is the manufacturer's own statement rather than an independent audit, so read it as a claim rather than a finding.

The two headline claims, and the conditions attached

On plaque, Dyson says the CameraJet removes up to 69% more than market-leading premium electric toothbrushes in hard-to-reach areas. But the footnote makes that a laboratory test, in the brush's variable mode, against sonic electric toothbrushes.

On gums, Dyson claims 13 times more effect on gum health. It also says gums become twice as healthy in two weeks. Both figures are measured against a manual toothbrush, and both require Dyson's own mouth rinse.

Neither claim compares the CameraJet with a good electric toothbrush plus ordinary floss. But that is the comparison most buyers are making at £419.99. Dyson has not published it.

The brushing action is separate from the jet, though. Dyson calls it variable sonic oscillation. It changes the oscillation angle as you brush, so the bristles never stall against the surface of a tooth.

What is in the box

• Dyson CameraJet electric toothbrush with flosser
• CameraJet refill dock, in Steel violet
• CameraJet USB-C to pogo-pin cable
• CameraJet lithium-ion battery
• CameraJet dual-bristle brush heads, pack of two
• CameraJet transparent travel case
• CameraJet anti-gravity tank
• CameraJet refill dock reservoir cap and base plate
• Dyson Spearmint starter kit

The dock holds 200ml, charges the brush and stands it upright. It also refills the tank in three seconds at the press of a button.

Brush heads, toothpaste and mouth rinse

The heads are dual-bristle. Firmer bristles sit on the inside for surface stains, softer ones on the outside for the gumline. Each head carries an RFID tag. So the brush counts the cleans it has done, then tells you when that head is finished. A target lens on the head then widens the camera's field of view. There is a sensitive version as well.

The toothpaste is non-foaming and made without SLS, because foam blinds the camera. The mouth rinse is low-foaming for the same reason. Both also carry sodium fluoride, phosphates and xylitol. Toothpaste comes in Spearmint and Ginger mint, with a Peppermint sensitive version alongside. The mouth rinse comes in Spearmint and Ginger mint.

Dyson does not say the brush refuses other toothpaste. It does say its own formulations let the camera see. That is why a tube and a bottle arrive in the box.

What the Dyson CameraJet costs to run

Dyson's default subscription sends one pack of two heads every six months at £22.50. Delivery is free and the saving is 10%, and you can pause or cancel at any point. So the head cost lands at £45 a year.

The mouth rinse is the figure Dyson has not published. The tank holds 12.5ml and the dock reservoir holds 200ml. But nowhere does Dyson say how many cleans a 400ml bottle covers. If a full tank went on every clean, twice a day, a bottle would last sixteen days. That is our arithmetic, and an upper bound on consumption rather than a Dyson number. Until Dyson publishes one, the running cost of a £419.99 toothbrush is the part you cannot price before you buy.

The returns catch, and it is the one to read twice

At first, thirty-five days sounds generous. But it applies only while the hygiene seal is intact. Dyson defines intact as the box unopened, with at least one tamper seal unbroken. Open the box and the return window has gone, whatever the calendar says. Dyson's wording is blunt: "Once the hygiene seal has been broken, the product is no longer eligible for return due to hygiene considerations."

So there is no try-it-and-see on a £419.99 toothbrush. You make the decision before anything comes out of the wrapping.

Toothpaste and mouth rinse run on their own rule: 14 days, unopened only. The return postage then comes out of the refund.

Guarantee and delivery

Electric toothbrushes carry a two-year Dyson guarantee on parts and labour. Dyson's main guarantee page still lists only vacuums, hair care, purifiers and lighting. So the two-year cover for oral care turns up in the money-back-guarantee panel on the product page instead.

Delivery is free and next-day on orders placed before 9pm, weekends included too. A list of mostly rural postcodes gets two working days instead. Every Northern Ireland postcode sits on that list. Dyson publishes the full set in its delivery terms.

What Dyson says it was trying to solve

James Dyson put the reasoning plainly in the launch announcement. "Flossing is an awkward and time-consuming chore. Few of us do it even though we know we should," he said. "Our research has shown that people consistently miss the areas where plaque forms: the gaps between teeth. We wanted to solve three fundamental problems: how to see those gaps, remove plaque, how to improve cleaning performance while brushing."

The figures behind it are unusual even by Dyson's standards. Six years, 661 engineers, 38 patents and 30 dental professionals. Then 16 million lines of code, and a model trained on 470,000 dental images. The NHS guidance on keeping your teeth clean still puts interdental cleaning alongside brushing rather than inside it. That second step is the habit this brush is trying to delete.

Dyson CameraJet FAQs

How much does the Dyson CameraJet cost?

It is £419.99 direct from Dyson, in either Ceramic Ultra Blue or Ceramic Pink. Delivery is free and next-day on orders placed before 9pm. Replacement heads then add £25 a pack, or £22.50 on Dyson's subscription.

Does it record video of the inside of your mouth?

Dyson says no, though the answer deserves reading closely. The camera runs only during live viewing or auto-jetting, and Dyson states that no images are recorded or stored on the product or in the cloud, and that they stay private to the user. That is Dyson's own account rather than an independent audit.

Can you return it if you do not get on with it?

Only if you have not opened it yet. Dyson gives 35 days, but a return needs the hygiene seal intact. That means an unopened box, with at least one tamper seal unbroken. Once you open it, the window has closed.

Do you have to use Dyson's toothpaste and mouth rinse?

Dyson does not say the brush blocks anything else. Its own toothpaste is non-foaming and SLS-free, because foam blinds the camera. The mouth rinse is low-foaming for the same reason. So a normal foaming paste sits between the lens and the gap it is hunting for.

How often do the brush heads need changing?

The head tells you when. An RFID tag counts the cleans that head has done, then flags it for replacement. Dyson's own subscription assumes one pack of two heads every six months, which works out at £45 a year.

How does it compare with the other electric toothbrushes we have listed?

It is a different proposition rather than a faster one, so the comparison is not straight. The Oral-B iO9 maps your mouth and coaches your brushing. The SURI sonic toothbrush costs £75 and is built to be repaired rather than replaced. Only the Dyson CameraJet does the flossing for you, and that single job is what the price is buying.

Is there a review of it on CoolCuration?

Not yet. This page is the reference layer, with the specifications, the prices and the terms. A separate opinion piece with a Cool Factor score follows later. It waits until we have used one long enough to say something honest.
