The $499 CameraJet is the first AI-powered toothbrush with a camera built into its brush head. In other words, it lets you livestream the inside of your mouth while you clean your teeth. It even offers feedback, like any good dentist. Six years and 661 engineers. A 100k-pixel macro-lens camera. An "anti-gravity tank." Yes, Dyson has put rather a lot into reinventing the toothbrush. There was once a time when bristles were enough. Glasses only needed lenses. Fridges kept things cold. Headphones played music. Increasingly, tech companies are putting cameras in everything. The CameraJet is not even tech's first trip to the bathroom. Once upon a time, toilets just needed to flush. Naturally, there is a subscription available, too. Dyson will happily keep you supplied with replacement brush heads, mouth rinse, and non-foaming toothpast
