Dyson Enters Oral Care Market with AI-Powered Toothbrush

Dyson is making its debut in the oral care market with an electric toothbrush that uses an AI camera to automatically clean between teeth. The company is expanding its product line by integrating its vision systems, machine learning, and fluid dynamics technology, which it has developed for its vacuum cleaners and hair care products.

On September 1, Dyson unveiled its first oral care system, the Dyson CameraJet electric toothbrush and oral irrigator, in Paris.

The standout feature of the CameraJet is its built-in camera, which identifies hard-to-see areas between teeth for cleaning. Dyson explained that after over a decade of research into oral hygiene habits and the accumulation of bacteria in the mouth, it focused on developing a product that addresses the management of interdental spaces where plaque tends to form.

The core technology is the AI machine learning-based 'Gap Optical Targeting' camera system. During development, the system was trained on 470,000 images of teeth, and a 100,000-pixel macro lens camera analyzes 28 images per second.

Based on this data, the AI algorithm predicts the location and orientation of spaces between teeth. When the camera detects an interdental space, it automatically sprays a cone-shaped stream of liquid toward that point within 0.1 seconds to remove plaque. The liquid is designed to spread widely, minimizing irritation to the gums.

The toothbrush's cleaning performance has also been enhanced. The three-dimensional sonic brush features firm bristles on the inside and softer bristles on the outside. The inner bristles remove surface stains, while the outer bristles clean along the gum line.

The sonic motor vibrates 245 times per second, allowing the bristles to move in a three-dimensional manner. An RFID tag on the brush head detects connectivity and usage frequency, notifying users when it's time for a replacement.

Smart features are supported through Wi-Fi and Bluetooth. Users can view their mouth in real-time via the 'MyDyson' app, which utilizes the camera mounted on the device. The camera activates only during live view or automatic jet spray functions, and the images captured are not stored on the device or in the cloud, according to the company.

James Dyson, the founder and chief engineer of Dyson, stated, "We found that many people overlook the interdental spaces where plaque forms. By combining a camera, machine learning, fluid dynamics, and advanced brushing technology with Wi-Fi, we are presenting a new solution for maintaining oral health."

The CameraJet will be available in two colors: Ceramic Pink and Ceramic Ultra Blue. The suggested retail price in South Korea is 749,000 won, and pre-orders began on September 1 through Dyson's official website and online channels.
