Dyson is entering oral care with the $499 CameraJet, a smart toothbrush that uses a tiny camera and on-device AI to detect gaps between teeth and automatically blast them with mouthwash while you brush. Regular toothpaste and mouthwash will work with the CameraJet, but Dyson plans to sell its own non- or low-foaming formulas designed to give the toothbrush's camera a clearer view inside your mouth. The Verge reports: Just below the brush head is a tiny camera with a 100,000-pixel resolution and a strobing light. The toothbrush's AI analyzes 28 live images from the camera every second as part of a feature Dyson calls Gap Optical Targeting, without storing them on the device or sending them to the cloud. Within 100 milliseconds of a gap between your teeth being detected, the CameraJet emits a cone-shaped blast of mouthwash to clean out the space. Dyson uses a wider blast than what water flossers typically employ so it can effectively remove plaque with less pressure, making the CameraJet's flossing mechanism gentler on enamel and gums The replaceable brush heads use a combination of softer outer bristles that safely clean along the gumline and stiffer inner bristles that are better at scrubbing away tooth stains. The brush head oscillates nearly 1,000 times each second while the angle of oscillation is constantly changing to improve the effectiveness of your brushing. Pricing on replacement brush heads isn't known, but each one features an RFID tag so the CameraJet can track usage and alert you when a replacement is needed every three months. To ensure its mouthwash reservoir can effectively pump no matter how the CameraJet is held -- even upside down -- instead of sticking a tube into the reservoir, there's an air bladder inside the tank that slowly inflates to fill empty space, minimize air pockets, and maintain a constant pressure. An elaborate docking station recharges the toothbrush and can automatically fill its built-in 12.5ml mouthwash reservoir in just three seconds.
