Artificial intelligence has already become part of kitchens, workplaces, and creative environments. Now, it is entering the bathroom through an unusual innovation: a toothbrush that detects the spaces between teeth and automatically directs liquid jets toward them.
Introduced on September 1, 2026, the Dyson CameraJet combines a macro camera, AI, and a targeted jet system to clean between teeth as users brush.
Priced at $499.99 in the United States, the device represents Dyson’s first entry into the oral-care market.
I can also make this version more journalistic, concise, or suitable for a science and technology article.
Inside the brush head, a 100,000-pixel macro camera captures 28 images every second as the user brushes.
AI Tracks the Gaps Between Teeth
Dyson’s Gap Optical Targeting machine-learning system processes the footage, detects and tracks the spaces between the teeth, and predicts where those gaps will appear.
When the system identifies one of these areas, the toothbrush releases a cone-shaped stream of mouthwash toward it in as little as 100 milliseconds. This targeted jet removes plaque from areas that bristles struggle to reach while the user continues brushing normally.
Dyson trained the technology on more than 470,000 dental images, while engineers built the complete product with roughly 16 million lines of code.
The camera serves a purpose beyond directing the liquid jets.
The CameraJet pairs with the MyDyson app, enabling users to see images of their mouth as they brush and receive guidance on their brushing technique.
Dyson says the captured images are not stored or shared. Image processing occurs directly on the device or through the app, and the company claims that neither it nor third parties can access the footage.
Smart Features Go Beyond the Camera
Beyond its camera system, the toothbrush includes Wi-Fi connectivity, built-in sensors, and an RFID-equipped brush head that detects when the bristles need replacing.
Dyson describes the technology using terms such as “liquid flossing” and “precision-flossing,” although its approach differs from conventional flossing, which involves physically passing a thread between the teeth.
The CameraJet contains a 12.5 ml mouthwash reservoir and releases a wide, cone-shaped jet toward the interdental spaces detected by its camera.
To develop and evaluate the system, Dyson spent five years collaborating with the Faculty of Dentistry at the National University of Singapore. The partnership involved creating an artificial plaque material for testing.
According to Dyson, the conical jet was selected because it removed more of this test plaque than the narrower streams commonly used in oral irrigators. However, the comparison took place in a laboratory and relied on specially developed testing material.
The level of engineering behind the device is considerable.
Dyson says the CameraJet required six years of development, involving 661 engineers and 30 dental professionals, and generated 38 patent applications.
Beyond the AI technology, the company created an oscillating bristle system that helps keep the bristles moving even when pressed against the teeth. Its charging base can also recharge the toothbrush and refill its liquid reservoir in roughly three seconds.
Specially Designed Oral-Care Products Keep the Camera Clear
The product range also includes non-foaming toothpaste and low-foaming mouthwash, specifically designed to keep bubbles from blocking the camera’s view.
The CameraJet offers an interesting example of a growing trend in consumer technology: computer-vision systems trained for a highly specific task and directly connected to a physical action.
Here, the AI does not need to chat, write text, or create images. Its job is much narrower: continuously identify the spaces between teeth and activate the cleaning mechanism at exactly the right moment.
The product also demonstrates how embedded AI differs from the large, general-purpose models that dominate today’s AI landscape.
Rather than trying to handle a wide range of tasks, this type of AI is designed to perform one specific function quickly and seamlessly enough to become almost invisible to the user.
Whether the combination of a camera, AI, and interdental cleaning provides enough value to justify a toothbrush costing nearly $500 remains to be seen. Dyson has published clinical and laboratory testing results on its website, but real-world use after the product’s market launch will offer a clearer picture of its effectiveness.
