Dyson launches £420 toothbrush with live‑mouth camera

techSep 1, 202620230

Dyson unveiled a £420 electric toothbrush that streams live footage from inside the mouth using a 100k pixel macro lens camera and shows the video in the MyDyson app. The toothbrush, launched by James Dyson at an event in Paris, took six years and 661 engineers to develop and includes an integrated “anti-gravity” mouthwash tank and a stem-mounted jet that fires rinse when the camera detects gaps between teeth. Dyson describes the camera as a “high-quality endoscope” and says the brush combines machine learning, precision fluid dynamics and advanced brushing technologies to guide users and give feedback on their cleaning. Dyson claims the device removes up to 72% more plaque than market leading electric toothbrushes; the company is marketing a non-foaming toothpaste and mouth rinse that each cost £8.50 so the camera lens is not obscured. The launch positions Dyson in an already crowded oral-care market where the Phillips Sonicare DiamondClean is sold for about £600, and the British Dental Association chair Eddie Crouch warned that gadgets are no substitute for a proper routine. Dyson also noted its team spent over a decade studying oral care and developed a proxy plaque for testing plaque removal accuracy.
