British firm Dyson has once again demonstrated that innovation knows no bounds. After revolutionizing the world of vacuum cleaners, hair dryers, and even air purifiers, the company founded by James Dyson has set its sights on an unexpected territory: oral care. The result is the Dyson CameraJet, an electric toothbrush that integrates a camera, artificial intelligence, and an automatic irrigation system to clean between teeth while the user brushes. According to the brand itself, this device is the culmination of six years of development, 661 engineers, and 38 registered patents.
The official launch took place on September 1st in Paris, where James Dyson unveiled a product that is sure to turn heads. The CameraJet is more than just an electric toothbrush: it incorporates a 100.000-pixel macro micro-camera under the brush head, a 12,5-milliliter mouthwash reservoir, and a computer vision system that analyzes 28 images per second. The goal is clear: to detect interdental spaces and fire a conical jet of mouthwash in just 100 milliseconds, right before the brush head passes over them. This engineering solution promises to put an end to the tedious task of flossing, a habit that, according to company data, nine out of ten people don't practice as often as recommended.
A real problem: the oral hygiene we neglect.
Dyson's starting point makes perfect sense. According to data presented by the company, the average time we spend brushing our teeth is around 45 seconds, well below the two minutes recommended by dentists. Furthermore, the area that almost everyone skips is precisely where plaque begins to form: the spaces between the teeth. The context is significant: the WHO's 2025 State of Global Oral Health report estimates that nearly 3.700 billion people worldwide suffer from some form of oral disease.
Dyson's answer to this consistency problem essentially involves taking the decision off the user's shoulders. The Gap Optical Targeting system, based on a machine learning algorithm trained on more than 470.000 dental images, identifies interdental spaces and anticipates when the brush will pass in front of one. Within 100 milliseconds of detection, it fires a conical jet of mouthwash precisely at that spot. The device's software comprises 16 million lines of code, a figure that clearly demonstrates the technical complexity hidden within this small device.
This is how the irrigation system and the chamber work
One of the most striking aspects of the CameraJet is its irrigation system. Unlike conventional oral irrigators, which use a needle-like water flow with a narrow laminar profile, Dyson has opted for a wider, conical projection. According to tests conducted on a dental plaque model developed in collaboration with the College of Dentistry at the National University of Singapore, this design allows plaque to be removed in a single pass and, because it is optimized to operate at lower pressure, is gentler on gums and tooth enamel.
The 12,5-milliliter reservoir uses an anti-gravity system with a diaphragm pump and pressure chamber that adapt during use. This ensures consistent performance regardless of the brush's position, even when held horizontally to reach the back of the mouth. The charging base allows the reservoir to be refilled in just three seconds with the touch of a button, making daily use easier. Additionally, the device incorporates a pressure sensor to prevent the user from applying excessive pressure against the enamel.
Connectivity, privacy, and its own ecosystem
The CameraJet's camera isn't just for helping artificial intelligence find interdental spaces. Thanks to Wi-Fi and Bluetooth connectivity, users can see live footage from the MyDyson app of what the brush is seeing inside their mouth. While this feature might seem confusing at first, it offers undeniable benefits: discovering which areas we clean correctly and which we tend to overlook. The app provides coverage maps, guides, explanatory videos, and personalized information to help users progressively improve their brushing technique.
Regarding privacy, Dyson has been very clear. Rich Bacon, Head of New Product Development at the company, explained that "we understand people's privacy concerns and the apprehension that having a camera in the bathroom might cause." Therefore, the images are neither recorded nor stored on the device, on the user's mobile phone, or in the cloud. The camera is only active during live viewing or automatic irrigation, and a white LED illuminates whenever it is on to alert the user.
Another important detail is that the CameraJet comes with its own ecosystem of consumables. The toothpaste has been formulated without SLS to produce minimal foam and prevent interference with the Gap Optical Targeting system, while the mouthwash also features a low-foaming formulation designed to work with the integrated irrigator. Both contain sodium fluoride and will be available in Ginger Mint and Spearmint flavors, as well as a Peppermint Sensitive toothpaste for sensitive teeth. This move is reminiscent of the ink cartridge strategy used in printers, but applied to dental care.
Price and availability in Spain
The Dyson CameraJet is now available on the official Dyson Spain website for €479. The kit includes the toothbrush with integrated water flosser, charging base, Dyson toothpaste and mouthwash, and a travel case. It is available in two colors: Ceramic Ultra Blue and Ceramic Pink. Each brush head incorporates an RFID tag that records the number of cleanings performed and alerts you when it's time to replace it, with an approximate replacement interval of three months.
The price undoubtedly places the CameraJet in the high-end market, well above premium electric toothbrushes from brands like Philips Sonicare or Oral-B. However, Dyson justifies the difference with the camera, the jet system, and the connectivity, arguing that it's not just a simple toothbrush, but a technological platform for oral care. It remains to be seen whether consumers are willing to pay that premium for a product that, ultimately, promises to improve a habit most of us neglect daily.
In short, the Dyson CameraJet represents a bold attempt to reinvent one of the most everyday and universal gestures: brushing your teeth. With its combination of camera, artificial intelligence, precision irrigation, and connectivity, the British company aims to transform an automatic ritual into an informed and personalized experience. The price is high, and the closed ecosystem may raise concerns, but no one can deny that Dyson has once again demonstrated that well-applied engineering can transform even the most basic objects in our daily lives. The question is no longer whether we needed a toothbrush with a camera, but whether we are willing to pay for it.
