The Toothbrush That Finally Watches What Flossing Never Could

Dyson

Nine out of ten people don't floss. Not because floss doesn't work — because flossing is slow, fiddly, and the easiest step to skip after a full day. Dyson spent six years, 661 engineers, and 38 patents trying to close that exact gap: the space between your teeth no bristle can reach, and most of us never bother clearing with anything else.

a camera where you'd least expect one

The CameraJet™ hides a 100k-pixel macro lens behind the bristles, paired with a dome-shaped lens that widens its view and captures 28 images every second while you brush. Dyson calls the tracking system Gap Optical Targeting — an algorithm trained on 470,000 dental images that finds the space between your teeth in real time and fires a precision jet into it within 100 milliseconds. It isn't recording you. The images process on-device and disappear before you've rinsed and spit.

flossing, disguised as brushing

The jet is conical, not the needle-spray you'd expect from a water flosser — it dispenses about 0.15ml per gap in a tenth of a second, engineered specifically to clear plaque without wearing down gums or enamel over time. Pair that with a dual-bristle head oscillating 245 times a second and Dyson claims up to 69% more plaque removal in the exact spots most people never reach. Three modes — brush, floss, or both — mean two minutes now covers what used to take four.

the case for collapsing the ritual, not adding to it

CameraJet™ is IPX7-rated, holds about ten days of charge on a swappable battery, and docks with a three-second refill — the kind of detail you only notice once you stop thinking about it at all. At $499, launching September 1st in Ceramic Ultra Blue and Ceramic Pink, it isn't cheap. But it's the rare gadget built to shorten a routine instead of lengthening it, with the National University of Singapore's Faculty of Dentistry and thirty dental professionals behind the engineering — more validation than most bathroom counters ever see.
