Dyson’s next product isn’t a vacuum or a hairdryer — it’s a toothbrush with a camera built into the head. The Dyson CameraJet was unveiled by James Dyson in Paris on September 1 and went on sale in the US the same day at $499.99. At its center is something Dyson calls Gap Optical Targeting — a sensor that hunts for the gaps between your teeth and fires a jet of liquid the moment it finds one.
The idea flips how oral care usually works. Instead of a brush that just spins faster or vibrates harder, CameraJet’s head shoots roughly 28 images per second, feeding a small onboard machine-learning model that spots the exact spots between teeth where food and plaque hide — the same spots most people skip when they brush by feel. Once it finds a gap, it fires a burst of liquid there automatically. It’s less “better toothbrush” and more “a toothbrush that does the flossing for you.”
Here’s the part that makes this more than a gimmick: adding a camera forced Dyson to redesign the products around it. Regular toothpaste foams up, and foam blocks a camera’s view. So the filing describes a companion set — a low-foam toothpaste and a low-foam rinse — built specifically so the lens never loses sight of your teeth. A single sensor change rewired the entire product line sitting next to your sink — the same way pulling one ingredient out of a cereal box forces everything around it to change. That is the part of Dyson CameraJet worth watching.
There’s also a trust question baked into a camera you put in your mouth. Dyson’s answer is that the images are processed on the device or in the MyDyson app, never stored or shared, and inaccessible to Dyson or anyone else at any point. That’s a clear position, which is more than most connected devices offer. Whether buyers take a company at its word on a camera pointed inside their body is a different question — and one the whole category will keep facing.
My take: Change one sensor, and the whole bathroom shelf has to follow.
