Dyson launches £420 toothbrush that films ‘live cleaning footage’ inside your mouth

Dyson has unveiled a £420 toothbrush equipped with a high-resolution camera capable of streaming live footage inside the user’s mouth during brushing. The product, named the Dyson CameraJet, combines advanced imaging technology with precision fluid dynamics to enhance oral hygiene. The toothbrush was launched at an event in Paris by James Dyson, the company’s founder and chief engineer. According to Dyson, the device takes six years and the work of 661 engineers to develop, incorporating a “100k pixel macro lens camera” and an “anti-gravity (mouthwash) tank.” The toothbrush includes a “high-quality endoscope” that allows users to view their mouths in real-time through the MyDyson app. This feature enables users to observe areas where plaque builds up, providing feedback on their brushing technique. When the camera detects gaps between teeth, the toothbrush triggers a jet of mouth rinse to remove plaque effectively. Dyson claims the device can remove up to 72% more plaque than leading electric toothbrushes. The product is part of a broader dental system that includes non-foaming toothpaste and mouth rinse, priced at £8.50 each. These items are designed to avoid obstructing the camera lens. Dyson highlights that the toothbrush addresses common challenges such as missed plaque buildup between teeth and the difficulty of flossing. By integrating machine learning, connectivity, and advanced brushing technologies, the company aims to offer a comprehensive approach to oral care. Dyson’s entry into the dental market comes amid competition from other high-end toothbrushes, such as the Philips Sonicare DiamondClean, which retails for £600. However, the British Dental Association (BDA) cautions against relying solely on expensive devices for oral health. Eddie Crouch, the BDA’s chair, emphasized that following a dentist’s advice and maintaining a regular brushing routine is essential, regardless of the tools used. The development of the toothbrush involved extensive research into oral care practices and the accumulation of plaque. Engineers developed a “proxy plaque” to test the effectiveness of plaque removal accurately. Sir James Dyson noted that many people fail to clean the spaces between their teeth, prompting the creation of a solution that combines visual feedback with targeted cleaning mechanisms. The toothbrush’s AI-powered camera scans 28 live images per second as the user brushes, identifying gaps between teeth quickly. Once detected, a conical jet of mouth rinse is activated within 0.1 seconds to clean these hard-to-reach areas. This innovation aims to simplify flossing and improve overall oral hygiene. Dyson’s previous ventures into personal care include hair dryers, straighteners, and air purifiers, reflecting the company’s diversification beyond traditional home appliances.
