Dyson Unveils First Electric Toothbrush with Built-In Macro Camera and Targeted Water Jet

Dyson has entered oral care with a toothbrush that uses a 1mm² macro camera to locate gaps between teeth and aim a mouthwash jet at them.

The CameraJet electric toothbrush took six years to develop, involving 661 engineers and 38 patent applications, according to Dyson. Its Gap Optical Targeting system and AI algorithms analyze up to 28 live images per second. The company says the device can recognize an interdental space in as little as 0.1 seconds, then activate the jet automatically with LED lighting to improve visibility.

The design combines brushing, water flossing and rinsing in one process. A 12.5ml anti-gravity capsule reservoir uses air pressure to keep the water stream stable when the brush is held upright, tilted or upside down. Each spray releases about 0.11 to 0.15ml of mouthwash. The 21-degree cone-shaped jet covers a wider area than a traditional needle-shaped stream, which Dyson says may help remove plaque while reducing pressure on the gums and enamel.

The brush head uses two types of bristles. A firmer blue inner layer targets tooth surfaces and stains, while softer green bristles clean along the gumline. An RFID chip records usage and reminds users when to replace the brush head. Dyson also says its variable-frequency sonic vibration can remove up to 69% more plaque than other premium electric toothbrushes in some hard-to-clean areas when brushing alone.

The MyDyson app connects through Wi-Fi and Bluetooth, showing live camera images and offering guided cleaning, coverage records and personalized feedback. Dyson says the camera operates only during live viewing or automatic spraying, and that oral images are not stored on the toothbrush or in the cloud. The product is available in Mist Rose and Aurora Blue for NT$16,990 through Dyson’s online store and department-store counters across Taiwan. Early buyers receive a mint toothpaste gel and mouthwash set while supplies last.
