Dyson is breaking into the oral care market with a £419.99 toothbrush that uses artificial intelligence (AI) technology and precision fluid dynamics to floss gaps between teeth while brushing.
The vacuum technology business’ six-years-in-the-making CameraJet dual-bristle toothbrush features a jet to target plaque in-between teeth, while a camera with AI-powered Gap Optical Targeting technology acts as a high-quality endoscope to identify gaps that need to be precision-flossed.
“Flossing is an awkward and time-consuming chore,” said James Dyson, founder and Chief Engineer of Dyson.
“Dyson engineers and scientists have spent well over a decade understanding oral care regimes and how nasties build up in the mouth.

“Our research has shown that people consistently miss the areas where plaque forms: the gaps between teeth.
“We wanted to solve three fundamental problems: how to see those gaps, remove plaque [and] how to improve cleaning performance while brushing.
“By combining a camera, machine learning, precision fluid dynamics, advanced brushing technologies, connectivity and wifi, Dyson CameraJet introduces an entirely new way to keep your mouth healthy.”
Inside the toothbrush’s camera is a 100k-pixel macro lens powered by machine learning which detects, tracks and predicts gaps between teeth in real time, triggering a precision jet burst of mouthrinse exactly where it is needed.
This AI technology scans 29 live images per second to detect, track and predict gaps between teeth that need flossing in real time, allowing users to see what their dentist sees via the live viewing feature in the company’s MyDyson app.
The CameraJet runs on 16 million lines of code, and a machine learning system trained on 470,000 dental images collected during development.
The camera is only active during live viewing or auto-jetting, with no images recorded or stored on the product or in the cloud.

Dyson’s broad Conical Jet, meanwhile, claims to jet sweep away plaque with wider coverage, but at a lower pressure to be gentler on gums and enamel.
The company’s fluid dynamicists spent years optimising the profile of the jet to remove plaque more effectively, and even developed their own proxy plaque through a five-year collaboration with the National University of Singapore’s Faculty of Dentistry.
This enabled engineers to iterate quickly and optimise for plaque removal, without requiring a clinical trial every time a change was made.
The toothbrush also features a compact, anti-gravity 12.5ml mouthrinse tank that dispenses the optimal amount of product for one session, integrating rinsing into a user’s brushing routine without flooding the mouth.
It comprises a diaphragm pump and pressure chamber that adapts during use to deliver controlled, uninterrupted jets in any orientation.
The dual-bristle toothbrush head also comprises Dyson’s Variable Sonic Oscillation technology, which varies the angle of oscillation while brushing to keep bristles in constant motion and to prevent stalling.
The Dyson CameraJet toothbrush comes with a docking station that refills the toothbrush with mouthwash at the touch of a button in just three seconds, while also charging the device in between cleans.
Dyson has also launched its own-brand dental system alongside the toothbrush, which includes a mouthwash and proprietary non-foaming toothpaste, formulated without common foaming agent SLS.
The brand claims this helps keep foam out of the way so the toothbrush’s camera can see clearly to support its Gap Optical Targeting technology.
Dyson’s toothpaste and mouthrinse both contain sodium fluoride to help fortify enamel and strengthen teeth, alongside phosphates and xylitol to target the bacterial source of plaque and tartar.
They are available in two flavours: Ginger Mint and Spearmint.
The Dyson CameraJet Dental System is available to purchase at dyson.co.uk.
The system includes the Dyson CameraJet toothbrush, charging dock, travel case, Dyson Toothpaste and Dyson Mouthrinse.
