Dyson is expanding into oral care with a $499 smart toothbrush that uses a built-in camera and targeted liquid jet to clean between teeth.

The CameraJet, which launches on Tuesday, uses a 100,000-pixel macro camera and artificial intelligence to identify gaps between teeth and automatically directs mouthrinse toward them.

The $499 device marks Dyson's latest expansion beyond the vacuum cleaners and hair care products for which the company is best known, adding another high-priced consumer product to its lineup as it looks to bring its engineering-heavy approach into a category already crowded with conventional electric toothbrushes and water flossers.

Dyson says the camera can analyze 28 images per second. Its software can trigger the jet within 100 milliseconds of detecting a gap.

The CameraJet uses a conical liquid jet rather than the narrow stream found on traditional water flossers. Dyson says the system is designed to remove plaque between teeth while operating at lower pressure.

A 12.5-milliliter reservoir holds mouthrinse, while an included dock can refill the tank in about three seconds, according to the company.

Users can connect the device to the MyDyson app for live camera viewing, cleaning guidance, coverage maps and feedback on brushing technique.

Dyson says images are not stored or shared and that processing takes place on the device.

The company also says laboratory testing found the CameraJet removed nearly 70% more plaque in hard-to-reach areas than premium electric toothbrushes under certain test conditions. Dyson conducted the testing using proxy plaque developed through research with the National University of Singapore.

Dyson is also developing low-foaming mouthrinse and SLS-free toothpaste for use with the device, suggesting the product is meant to be used as part of a broader oral-care system rather than as a standalone gadget.

The CameraJet is available through Dyson's website and Dyson Demo Stores.
