How the CameraJet’s imaging technology works
Dyson has introduced the CameraJet, an AI-powered toothbrush priced at $499, featuring a 100,000-pixel macro lens that captures 28 images per second to analyze oral health in real time. The device was unveiled on September 1, 2026, marking Dyson’s entry into the smart personal care market with a focus on preventive dental technology. The CameraJet connects to a companion app that uses machine learning to detect early signs of plaque, gum inflammation, and enamel wear, offering personalized brushing feedback. It is designed for daily use and aims to transform routine oral hygiene into a data-driven health monitoring tool.

These images are processed instantly by an onboard AI chip that compares them against a database of dental conditions trained on thousands of clinical images. The system identifies subtle changes invisible to the naked eye, such as early demineralization or micro-fractures, and alerts users via haptic feedback and app notifications. Dyson claims the technology can improve brushing effectiveness by up to 40% compared to standard electric toothbrushes by guiding users to missed areas. The device also tracks brushing pressure, duration, and coverage, generating a weekly oral health score.
Can this toothbrush replace regular dental visits?
While the CameraJet provides detailed daily monitoring, Dyson emphasizes it is not a substitute for professional dental checkups or cleanings. Instead, it is intended to complement clinical care by giving users and dentists actionable data between visits. Early adopters have reported increased awareness of brushing habits, with some noting reduced bleeding gums after two weeks of use. Dental professionals consulted during development noted the potential for such devices to encourage preventive behavior, especially among users who skip routine appointments. However, they caution that AI interpretation of oral images should always be validated by a licensed dentist, particularly for diagnostic decisions.
How long does the CameraJet battery last on a single charge? The CameraJet offers up to 14 days of use on a full charge, with a magnetic charging dock that fully recharges the device in three hours.
Frequently Asked Questions
Is the CameraJet safe to use with braces or dental implants? Yes, the device is safe for use with braces, implants, crowns, and other dental work, as the bristles are soft and the imaging system does not emit radiation or heat.
Does the CameraJet store images of my mouth? All images are processed locally on the brush and are not uploaded to the cloud unless the user explicitly enables data sharing for research or app improvements, with end-to-end encryption applied.
