Dyson, the company known for reimagining everyday household appliances, is now turning its engineering prowess to oral care. The result is the CameraJet, a $499 electric toothbrush that combines a camera, artificial intelligence, and a precise mouthwash delivery system to automate flossing. Available from today in ceramic blue or ceramic pink, the CameraJet marks Dyson's first foray into dental hygiene, promising a deep clean while eliminating the hassle of traditional flossing.

A camera inside your mouth

At first glance, the CameraJet looks like a sleek, futuristic toothbrush. But just below the brush head sits a tiny camera with a 100,000-pixel resolution and a strobing LED light. This camera is not there just for show; it streams a live view of the inside of your mouth over Wi-Fi to a paired smartphone, allowing you to see exactly what a dentist would see. This feature alone could appeal to those who have always wondered what is happening in the hard-to-reach corners of their mouths.

The camera's strobe light serves a practical purpose: it helps produce stabilized images that the toothbrush's onboard AI can analyze. Every second, the system captures 28 live images, processing them in real time to identify the tiny gaps between teeth. Dyson calls this feature Gap Optical Targeting. The processing happens entirely on the device, meaning no images are stored or uploaded to the cloud, addressing potential privacy concerns eager gadget lovers might have.

Automated flossing with mouthwash

When the AI detects a gap between teeth, the CameraJet springs into action. Within 100 milliseconds, it emits a cone-shaped blast of mouthwash directly into the interdental space. This is not a random spray; the intensity and direction are carefully calibrated to remove plaque and food particles effectively. Unlike traditional water flossers that rely on a thin, high-pressure jet, Dyson uses a wider cone of liquid. This broader spray distributes pressure more evenly, making the flossing mechanism gentler on enamel and gums while still being effective at cleaning.

For many people, flossing is an easily skipped step in their daily routine. The convenience of having a toothbrush that does it automatically could be a game-changer. Dyson's approach echoes its philosophy of applying engineering innovation to solve common problems, just as it did with its bladeless fans and cordless vacuum cleaners.

Brush head design and oscillation

The replaceable brush heads of the CameraJet feature a combination of bristles designed for different cleaning tasks. The softer outer bristles are gentle on the gumline, while the stiffer inner bristles are better suited to scrubbing away tooth stains. The brush head oscillates nearly 1,000 times per second, and the angle of oscillation constantly changes to maximize the cleaning coverage. This dynamic movement helps reach areas that a standard electric toothbrush might miss.

Each brush head includes an RFID tag that allows the toothbrush to track usage. When it is time for a replacement—typically after three months—the CameraJet will alert you. This is a smart way to ensure that users maintain optimal brushing hygiene, as many people continue using worn-out brush heads far longer than recommended. While Dyson has not yet announced pricing for the replacement heads, they will likely be a recurring cost, similar to other premium electric toothbrushes.

A mouthwash tank that works upside down

One of the engineering challenges Dyson faced was ensuring that the toothbrush's built-in mouthwash reservoir could dispense liquid reliably no matter how the brush was held. Users naturally rotate the brush, tilt it, and sometimes turn it upside down to reach the back teeth. A traditional tube-and-siphon system would fail in those positions, leaving air pockets that disrupt the flow.

Dyson solved this with an innovative air bladder inside the tank. The bladder slowly inflates as the mouthwash is used, filling the empty space and maintaining constant pressure. This design prevents air pockets from forming and ensures a steady, reliable blast of mouthwash every time, regardless of the brush's orientation. The reservoir holds 12.5 milliliters of mouthwash, and the accompanying docking station can recharge the toothbrush and refill the tank automatically in just three seconds. That kind of user-friendly convenience is typical of Dyson's attention to detail.

Dyson-branded consumables

While the CameraJet works with any regular toothpaste and mouthwash, Dyson recommends its own specially formulated products for the best experience. The company will sell a non-foaming toothpaste and a low-foaming mouthwash, both designed to keep the camera's view clear. Regular toothpaste and mouthwash create foam that can obscure the camera lens and interfere with the AI's ability to detect gaps between teeth. Dyson's low-foaming formulas are engineered to minimize this issue, allowing the camera to function more effectively throughout the brushing session.

This move mirrors Dyson's broader strategy of creating an ecosystem around its products. By selling proprietary consumables, the company can ensure a quality experience and establish a recurring revenue stream. It is similar to how Dyson offers filters and accessories for its air purifiers and vacuum cleaners.

Dyson's history of personal care innovation

The CameraJet is not Dyson's first step into the personal care arena. The company gained widespread attention in 2016 when it launched the Supersonic hair dryer, which used a digital motor and Air Multiplier technology to dry hair quickly without extreme heat. This was followed by the Airwrap styler in 2018, a device that uses the Coanda effect to wrap hair around barrels for curling and styling. The Corrale straightener, introduced in 2020, featured flexible copper plates that adapt to the thickness of the hair, reducing heat damage.

Dyson's jump from hair care to oral care might seem unexpected, but it is consistent with the company's mission to solve problems that traditional appliances often ignore. In the case of oral hygiene, the problem is that many people do not floss regularly, and even those who do often do it incorrectly. The CameraJet aims to make flossing automatic and effective, leveraging technology to deliver tangible health benefits.

Market context and competition

The premium smart toothbrush market has grown significantly over the past decade. Brands like Philips and Oral-B offer electric toothbrushes with Bluetooth connectivity, pressure sensors, and app-based brushing tracking. Prices for these devices typically range from $100 to $300. At $499, the CameraJet is positioned at the high end, but Dyson argues that its combination of a camera, AI, and automated flossing justifies the premium.

Compared to other high-end smart toothbrushes that only track brushing time and pressure, the CameraJet offers a unique feature set. The live video streaming alone is a differentiator, as it can reveal areas of the mouth that might need more attention. The automated flossing is another significant advantage, potentially reducing the time and effort required for a complete oral care routine.

However, the high price tag might be a barrier for many consumers. For those who already struggle to maintain a consistent brushing routine, spending $499 on a toothbrush could be a tough sell. Dyson's target audience is likely tech enthusiasts and early adopters who are willing to invest in a premium device that promises long-term oral health benefits.

Privacy and data security

One of the most innovative aspects of the CameraJet is its camera, but this also raises questions about privacy. The thought of a camera operating inside your mouth while you brush could be unsettling. Dyson has addressed these concerns by ensuring that all image processing occurs on the device. No images are stored in the toothbrush's memory or transmitted to the cloud. The live video stream is sent directly to your smartphone via Wi-Fi, and the phone app must be open for the stream to be viewed. This local processing approach minimizes the risk of data breaches or unauthorized access.

It is also worth noting that the camera is positioned to look forward from the brush head, so it is unlikely to capture anything other than the inside of the mouth and some of the face. Still, as with any connected device, users should be cautious about pairing their toothbrush with a smartphone and ensuring that their home Wi-Fi network is secure.

Potential drawbacks and limitations

While the CameraJet is an impressive feat of engineering, it is not without drawbacks. The first is the price, which may be prohibitive for many. The second is the reliance on Dyson's proprietary mouthwash and toothpaste for optimal performance. While the brush will work with regular products, foaming agents in conventional toothpaste can reduce the camera's effectiveness, which could be frustrating for users who prefer their own favorite brands.

Another limitation is that the mouthwash tank, while cleverly designed, holds only 12.5 milliliters. This might be enough for a single brushing session, but users will need to refill the tank regularly if they brush three times a day. The docking station's auto-refill feature mitigates this issue, but the station must be installed in a location with easy access to the mouthwash supply.

Finally, there is the question of whether the automated flossing is truly as effective as traditional flossing or water flossing. Dyson claims that the cone-shaped blast can remove plaque with less pressure, but independent clinical studies have yet to verify these claims. As with any new oral care technology, it is advisable to consult with a dentist before relying solely on the CameraJet for interdental cleaning.

Availability and first impressions

The CameraJet is available as of today directly from Dyson's online store. With its ceramic blue and ceramic pink finishes, it is clearly designed to be a stylish addition to any bathroom counter. The included charging dock, which also serves as a refill station, adds to the premium feel. But whether the CameraJet will become as iconic as Dyson's hair care products remains to be seen.

Early reactions from tech journalists have been mixed but generally positive. The innovation is undeniable, and Dyson's ability to integrate a camera, AI, and a liquid delivery system into a toothbrush is a remarkable engineering achievement. However, the practicality of a $499 toothbrush will inevitably polarize consumers. For those who hate flossing and have the disposable income, the CameraJet could be a worthwhile investment. For others, it might remain a curious gadget on the periphery of the oral care market.

As Dyson continues to expand its personal care ecosystem, the CameraJet represents a bold step into a new category. Whether it will capture the public's imagination like the Airwrap or face the same scrutiny as some of the company's more experimental devices, one thing is certain: Dyson is not afraid to take risks. By applying its engineering expertise to oral health, the company is challenging established players and forcing the industry to rethink what an electric toothbrush can be.
