[DigitalToday reporter Jae-won Choi (최재원)] Dyson has unveiled an electric toothbrush that uses a camera and AI to locate gaps between teeth and automatically spray cleaning liquid. Dyson, known for hairdryers and vacuum cleaners, has expanded its business into the oral care market.

On Sept. 1 (local time), Dyson launched CameraJet, an electric toothbrush that combines an electric toothbrush with a liquid floss function. It sells for $499.99 in the United States, or about 687,230 won. The device aims at consumers who often skip flossing by handling brushing and interdental cleaning with one device.

The key is the miniature camera inside the toothbrush. A 1 mm, 100,000-pixel macro camera shoots 28 images per second, and AI-based Gap Optical Targeting identifies gaps between teeth in real time. It then sprays up to 0.15 mL of water or oral rinse in a cone shape at the spot. The 12.5 mL tank is designed to dispense liquid steadily even when the toothbrush is tilted.

Privacy concerns were also raised as the camera goes into the mouth. Dyson said the camera footage is processed on the device or in the MyDyson app and is not stored or shared. It said the company or third parties cannot access the images. Users can also check the inside of their mouth in real time while brushing through the app if they want.

Home appliances with built-in cameras are already spreading to include video doorbells, robot vacuum cleaners and refrigerators. CameraJet is an example of extending that into bathrooms and oral care. It is unclear whether its high price of $500 will offer consumers enough value to replace existing electric toothbrushes and floss.

How much advanced sensors and AI can change everyday brushing habits is expected to determine CameraJet's success.
