7You tries Dyson’s new camera-powered $799 smart toothbrush. Here’s everything you need to know

But when I travelled to Dyson’s global headquarters in Singapore in June to get an early look at what the company had been doing in oral care, I was not prepared for what happened next.

I watched the Dyson CameraJet in action, and for once, the phrase ‘revolutionary’ did not feel like an overstatement.

The toothbrush has a camera and it uses machine learning to find the gaps between your teeth. Then, while you are brushing, it fires a precision jet of mouthrinse directly into those spaces.

And now, after months of having to keep what I saw under wraps, I can finally talk about it.

Launching in Australia tonight, the Dyson CameraJet is being positioned as an entirely new approach to oral care.

Rather than asking us to brush, floss and rinse as three separate jobs, Dyson has attempted to combine them into one connected system.

Inside the toothbrush is a 100,000-pixel macro lens camera powered by what Dyson calls Gap Optical Targeting.

It scans 28 live images every second, using machine learning to identify, track and predict the gaps between your teeth in real time.

Once it spots one, the system can trigger a precision burst of mouthrinse within 100 milliseconds.

In other words, it is looking for the places you are most likely to miss.

According to Dyson’s research , nine in 10 people do not floss as regularly as they should.

People also spend an average of just 45 seconds brushing, significantly less than the recommended two minutes.

The spaces between our teeth are particularly easy to neglect. They are also exactly where plaque can begin to build up.

Dyson’s answer is not simply to make a more powerful toothbrush. It has spent six years developing an entire dental system around the problem, involving 661 engineers, 30 dental professionals and 38 patents.
