Dyson, known for its vacuum cleaners, is now cleaning "teeth" with an unusual toothbrush equipped with AI and a camera.

The Era of Toothbrushes that "See, Think, and Clean" — Dyson's Next Target is the Human Mouth

Vacuum cleaners, air purifiers, hair dryers, hair stylers. The markets Dyson has entered so far share a common trait.

They are already mature product categories, fields perceived as having little room for further evolution. Dyson brings in technologies like motors, aerodynamics, sensors, and software to redefine them as premium products, far more expensive than traditional offerings.

The next target for Dyson is the "toothbrush," a tool almost everyone uses daily.

In September 2026, James Dyson announced the "Dyson CameraJet," which at first glance appears to be a high-end electric toothbrush.

However, the technology inside makes it hard to call it just a toothbrush.

It features a small camera at the tip, where AI recognizes the inside of the mouth and finds the spaces between teeth. The moment it reaches the necessary position, it jet-sprays mouthwash.

In other words, it is a product that attempts to consolidate multiple tasks—brushing, cleaning between teeth, and viewing the inside of the mouth—into one machine.

The philosophy Dyson honed with its vacuum cleaners—"find, target, and remove"—is now directed not at floors but at the human mouth.

A 100,000-pixel Camera Searches Between Teeth

The standout feature of the CameraJet is the small macro camera integrated near the brush head.

The resolution is 100,000 pixels.

Compared to smartphone cameras, this is not high resolution. However, the purpose of this camera is not to take commemorative photos but to recognize teeth, gums, and gaps from a very short distance of a few centimeters.

The camera analyzes 28 images per second.

The images obtained are processed by a machine learning system Dyson calls "Gap Optical Targeting," which detects gaps between teeth in real-time.

Once a gap is recognized, the system responds in about 100 milliseconds, jetting mouthwash from a nozzle built into the brush to the targeted spot.

Users simply move the brush like a regular electric toothbrush, with interdental cleaning automatically incorporated along the way.

Traditionally,

you would brush your teeth.

Use floss.

Sometimes use a water flosser.

Rinse with mouthwash.

These multiple steps were necessary.

CameraJet aims to reduce that hassle through technology.

Dyson focused not on the problem of "not knowing the correct oral care method," but on the human issue of "knowing but not being able to continue daily."

AI Trained on 470,000 Dental Images

CameraJet is not an experimental gadget created on a whim.

According to Dyson, about six years were spent on its development.

For the development of the machine learning system, approximately 470,000 dental-related images were collected. The software that operates the entire CameraJet consists of about 16 million lines of code.

Over 600 engineers were reportedly involved in the development, and dozens of patents related to the technology were filed.

For a toothbrush, this is an extraordinary scale.

However, this is characteristic of Dyson.

The company has traditionally viewed everyday products not as simple consumer goods but as "problems not yet sufficiently solved by engineering."

For vacuum cleaners, it was suction power and the visualization of dust.

For hair dryers, it was temperature control and high-speed airflow.

And for toothbrushes, the challenge was "how to discover places the brush doesn't reach," addressed with cameras and AI.

Why is Jet Spraying Necessary?

What sets CameraJet apart from ordinary smart toothbrushes is that it doesn't stop at just showing the inside of the mouth with a camera.

The moment AI discovers a gap between teeth, it sprays liquid onto that spot.

Dyson claims to have done considerable development for this fluid technology.

While many conventional water flossers use a thin, straight water stream, CameraJet employs a "Conical Jet" that spreads in a conical shape.

Instead of piercing a single point strongly, it is designed to apply liquid in a way that envelops a certain area.

This is an area where Dyson, with its long-standing research on fluids in vacuum cleaners and hand dryers, excels.

Additionally, the device houses a 12.5-milliliter mouthwash tank.

It is designed to stably dispense liquid whether the toothbrush is held vertically or horizontally, automatically spraying where the machine deems necessary during brushing.

It's not just a simple combination of a toothbrush and a water flosser; the camera acts as the eyes, AI makes decisions, and the fluid system executes them.

The essence of the CameraJet product is closer to that of a small robot.

Live Streaming the Inside of Your Mouth to Your Smartphone

Furthermore, CameraJet can connect to the MyDyson app.

It can display the footage captured by the camera in real-time on a smartphone, allowing users to check their teeth and gums.

Ordinarily, there are few opportunities to closely examine one's own molars.

Even with a mirror, there are limits to what can be checked.

With CameraJet, you can view your mouth at home in a way similar to using an intraoral camera at a dental clinic.

The app also provides confirmation of brushed areas, analysis of brushing conditions, and guidance.

Daily brushing could shift from being a mere habit to an act of improvement while checking data.

Just as smartwatches have visualized sleep and heart rate, Dyson aims to "visualize" oral care.

Concerns Arise About "Filming Inside the Mouth"

Naturally, when the idea of a toothbrush with a camera was announced, privacy concerns quickly emerged on social media.

Smart speakers, TVs, doorbells, glasses, cars.

Modern living environments already contain a plethora of cameras, microphones, and sensors.

Hearing "a camera in a toothbrush" might make some question the necessity of connecting everything to the internet.

On Reddit, there were many posts questioning the need to put cameras on every device and expressing suspicion that oral footage might be sent externally.

Meanwhile, Dyson has clearly explained its privacy measures.

The camera only operates when necessary functions are in use, and this is indicated by a light.

Live footage is sent to the smartphone but not stored in Dyson's cloud or the app.

Neither third parties nor Dyson can view the user's live footage.

In other words, CameraJet is designed to use the camera as a "sensor" for AI to make judgments on the spot, rather than a health data service accumulating oral footage.

Whether consumers feel reassured by this is another matter.

Safety as a function and psychological resistance are not necessarily the same.

For CameraJet to become widespread, it seems necessary to overcome the discomfort of having a camera in a toothbrush.

The Most Notable Reaction on Social Media: "A $500 Toothbrush?"

Beyond the camera, the price of CameraJet became a major topic of discussion.

 

The U.S. price is $499.99.

In the UK, it's reported to be around £420.

Depending on the exchange rate, this suggests a price range of 70,000 to 80,000 yen in Japan.

This is incomparable to a typical manual toothbrush and falls into a very high price range even among luxury electric toothbrushes.

Social media saw a flurry of posts expressing surprise at this price.

In the Reddit electric toothbrush community, while the camera feature itself was rated as "quite interesting," reactions like "500 dollars is a bit too much for me" were posted.

Conversely, some users saw a certain rationality in the price when considering the cost of separately purchasing a high-end electric toothbrush, water flosser, and oral camera.

Another user pointed out that combining a general electric toothbrush with an inexpensive water flosser could provide similar care at a much lower cost.

Thus, the debate is

whether to view it as "a $500 toothbrush"

or as

"a machine integrating a high-end electric toothbrush, flosser, and oral camera."

This is a debate that has been repeated many times with Dyson products.

Even the Term "100,000 Pixels" Became a Meme on Social Media

On Reddit, where many tech enthusiasts gather, the specification descriptions themselves became a topic of discussion.

Dyson describes the CameraJet's camera as a "100,000 pixel camera."

One user jokingly pointed out that writing "100,000 pixels" sounds more impressive than writing "0.1 megapixels."

This comment garnered a lot of reactions.

Regarding the specification of "analyzing 28 images per second," comments followed, mocking that it sounds more impressive than writing "28fps."

Of course, in reality, the CameraJet's camera is not for viewing entertainment.

As long as AI can determine the gaps between teeth, high pixel count is not necessarily required.

Still, the reactions show that consumers familiar with high-tech product specifications are looking at marketing terms with a critical eye.

There Are Certainly Voices Saying "I Want It"

Not all reactions were negative.

In dental hygiene communities, posts expressing a desire to own or try the CameraJet were observed.

The attempt to automate flossing is particularly appreciated.

For many people, while daily brushing is a habit, continuing with flossing daily is cumbersome.

With CameraJet, interdental cleaning could be completed while brushing as usual.

This aspect of "not requiring additional actions" is not just a tech demo but holds the potential to solve real-life problems.

One social media user, while surprised by the $500 price, evaluated it as understandable when considering the separate purchase of a high-end electric toothbrush and water flosser.

Additionally, a user believed to be a dental professional expressed interest in trying it to show patients.

In other words, while CameraJet may not be a "toothbrush for everyone," it could strongly appeal to those eager to try new gadgets or highly interested in oral care.

Dental Professionals Point Out That "Expensive Machines Alone Won't Solve Everything"

On the other hand, buying a high-functioning machine doesn't solve all oral care issues.

The Guardian reported that UK dental professionals pointed out the importance of daily care habits over expensive equipment.

This is an important point.

No matter how high-performance a toothbrush is, its effectiveness is limited if used infrequently.

Furthermore, preventing cavities and periodontal disease involves not just brushing but also diet and regular dental check-ups.

CameraJet is not a substitute for a dentist.

Its value might lie in enabling individuals to recognize unbrushed areas daily at home, which were previously pointed out at dental clinics every few months.

Dyson Wants to Sell More Than Just a "Toothbrush"

Another important aspect of viewing CameraJet is that Dyson aims to expand its product lineup as a "Dental System."

In addition to the CameraJet itself, Dyson offers dedicated brush heads, low-foam toothpaste, and low-foam mouthwash.

Too much foam from toothpaste can obstruct the camera's view.

Therefore, to maximize the performance of CameraJet, combining it with dedicated care products that make it easier for the camera to see is logical.

This is very interesting from a business perspective.

Once a vacuum cleaner is purchased, it may take years before the next replacement.

On the other hand, toothbrush heads, toothpaste, and mouthwash are consumed continuously.

If CameraJet users continue to purchase Dyson's oral care products, the company will enter a market where sales recur not just from device sales but as daily necessities.

CameraJet is not merely an "expensive toothbrush," but can also be seen as Dyson's entry point into building a new, subscription-like consumer market.
