If a toothbrush is going to target the gaps between teeth precisely, it first needs to see exactly where the liquid should go. CameraJet tackles that with a roughly 100,000-pixel macro camera, machine-learning-assisted gap detection and a targeted liquid jet. Dyson introduced the device in September 2026, and a live view of the mouth can be displayed through the MyDyson app.

To keep the camera's view clear, the system also uses specially designed low-foaming toothpaste. Adding imaging, recognition and liquid control to brushing turns even the toothpaste into part of the system design.
