FOX19 - A new toothbrush with a miniature video camera allows users to see inside their mouths while they brush.
The $400 Bluetooth-enabled Prophix was developed by a Chicago area dentist. He says the toothbrush, which is equipped with a light as well as a camera, allows users to clean the back teeth and molars better.
Studies show that 80 percent of people don't brush long enough in at least one part of their mouths.
The Prophix app also tracks how often and how thoroughly users brush.
