Dyson's £420 smart toothbrush streams live mouth footage and AI-guided cleaning

Dyson has unveiled a £420 smart toothbrush with a high-resolution endoscope camera that streams live inside-your-mouth footage to the MyDyson app, uses machine learning to detect gaps between teeth, and deploys mouthwash jets to target plaque, claiming up to 72% more plaque removal than leading rivals; the system includes a non-foaming toothpaste and mouth rinse and aims to position itself as a complete dental tech solution, though dental experts warn that a proper brushing routine remains essential.
