It’s the kind of footage nobody really asked for, but might struggle to stop watching: live video streamed directly from inside your own mouth while you brush your teeth. Dyson, the company best known for reinventing vacuums and fans, has now turned its attention to oral hygiene with an elaborate £420 toothbrush capable of cleaning, flossing, and even spraying tiny jets of mouthwash as you use it.
A toothbrush built with serious engineering behind it
Gone are the days when a simple handle and bristles would do the job, at least according to Dyson. The new toothbrush took a full six years to develop, involving the work of 661 engineers, and comes equipped with what the company calls a “100k pixel macro lens camera,” along with an “anti-gravity” mouthwash tank built directly into the device.
According to Dyson, the built-in camera functions as a real endoscope, letting users effectively see what their dentist would see during a routine check-up. Whoever’s brushing can watch live footage of their own cleaning session through the MyDyson app, receiving real-time feedback on how thoroughly they’re actually cleaning their teeth.

How the toothbrush was developed
The high-tech toothbrush was officially launched at an event in Paris by the company’s founder and chief engineer. He explained that engineers and scientists at the company, which relocated its corporate headquarters to Singapore back in 2019, spent well over a decade studying oral care routines and understanding exactly how plaque and bacteria build up inside the mouth. As part of that lengthy research process, the team even developed something described as a “proxy plaque,” a stand-in substance used specifically to test how effectively the brush removed plaque under controlled conditions.
Why flossing was such a big focus
Flossing, he noted, has always been an awkward, time-consuming chore that most people know they should do, yet consistently avoid. According to the company’s research, people repeatedly miss the exact areas where plaque tends to form most, the small gaps between teeth that a standard toothbrush simply can’t reach effectively on its own.
By combining a built-in camera, machine learning, precision fluid dynamics, and advanced brushing technology, along with wifi connectivity, Dyson claims the toothbrush offers an entirely new approach to keeping your mouth healthy, one that goes well beyond the traditional back-and-forth hand motion most of us grew up using.

How the technology actually works while brushing
When the onboard camera detects gaps between teeth, a small jet built into the toothbrush’s stem releases a burst of mouth rinse to help clear away plaque in real time as you brush, while the brush head itself works along the gum line, lifting surface stains as it goes. Dyson claims the toothbrush removes up to 72% more plaque compared to other market-leading electric toothbrushes currently available.
No proper dental routine would be complete without toothpaste, and Dyson is positioning this launch as a full “complete dental system” rather than a standalone product. That system includes a non-foaming toothpaste, specifically designed not to obscure the toothbrush’s built-in camera lens, along with a companion mouth rinse. Each of these additional products is priced separately at £8.50.
Stepping into an already crowded market
Dyson is entering a market that’s already fairly saturated with ultra-advanced toothbrushes, including plenty of existing smart models with their own companion apps, promising everything from plaque and stain removal through to tongue cleaning. The Philips Sonicare DiamondClean, available at retailers including Boots and John Lewis, already carries a price tag of £600, showing that premium pricing in this category isn’t new territory, even if Dyson’s specific camera-based approach is.
What dental experts actually recommend
For anyone without a large toothbrush budget, there’s reassuring news. The British Dental Association has been clear that expensive gadgets simply aren’t necessary for good oral health. According to the organisation’s chair, patients shouldn’t be lulled into believing the latest high-tech gadgets will single-handedly solve all their oral health problems. Big brand names carrying high price tags, he stressed, are no real substitute for following a dentist’s advice and maintaining a consistent brushing routine, twice a day, every day.
