Dyson oral care: does a high-tech toothbrush clean better?

Dyson, better known for vacuum cleaners and hair dryers, has moved into oral care with the CameraJet. It is an electric toothbrush that carries a tiny camera and a system that aims a jet of fluid between your teeth while you brush. It is a striking piece of engineering, and it has understandably generated a lot of curiosity. As a dental clinic, the question we are asked is a simpler one: does a cleverer, more expensive toothbrush actually give you cleaner, healthier teeth? Here is an honest answer, with no brand to sell.

What the Dyson CameraJet actually does

The headline features are a small macro-lens camera and a targeting system that detects the gaps between your teeth. As you brush, a jet then directs fluid into those gaps, aiming to disturb plaque where a brush alone struggles to reach. Dyson says it was developed with dental experts and tested in a clinical study. That is a genuinely novel combination, and it is fair to give credit where it is due: the idea of helping people clean between their teeth, which most of us do poorly, is a sensible target.

The part that has not changed

Here is the honest bit. The science of preventing decay and gum disease is not new, and no device rewrites it. Clean teeth come from a short list of unglamorous habits: brushing for two minutes twice a day, using a fluoride toothpaste, cleaning between the teeth every day, easing off on sugary snacking, and seeing a dentist regularly. Any toothbrush that helps you do those things more consistently is useful. No toothbrush that distracts from them is worth the money.

Electric versus manual: what the evidence really says

On average, powered toothbrushes remove a little more plaque than manual ones over time. But the reason is revealing: much of the benefit comes from the built-in timer, which nudges people to brush for the full two minutes rather than the forty-odd seconds most of us actually manage. In other words, the gain is largely about behaviour, not magic. A manual brush used with good technique for a full two minutes still cleans very well. We cover this in more detail in our guide to electric versus manual toothbrushes.

Where a high-tech brush can genuinely help

• If you rush and never brush for long enough, a timer and feedback can build a better habit
• If you find brushing awkward, a powered brush can do more of the work for you
• If you never clean between your teeth, a device that targets the gaps may be better than doing nothing there at all
• If the technology genuinely motivates you to brush more carefully, that motivation is worth something

And where to keep your expectations honest

• A jet between the teeth is a helpful extra, not a guaranteed replacement for floss or interdental brushes, especially around crowded teeth, crowns or bridges
• An app and a camera give you feedback, but they do not fix a technique problem on their own
• It is a premium product, and the cleaning gain over a simpler timed electric brush is smaller than the gain over a manual one
• It is brand new, so independent, long-term evidence is still limited; the current claims come largely from the maker's own testing

The honest verdict

If you like the technology and it will genuinely get you brushing better, twice a day, the Dyson CameraJet is a reasonable choice, as is any well-made electric brush. If you are hoping a clever gadget will make up for rushed brushing and skipped flossing, no device will do that. The best toothbrush, in the end, is the one you use properly and consistently. If you are not sure whether your brushing is actually working, that is a question a dentist can answer far better than a camera: at a check-up and clean we can show you exactly where you are missing and how to fix it. You can book an appointment whenever you would like an honest, brand-free opinion.
