Nanocomposite mouthguard highlights early signs of tooth decay
Material stops fluorescencing on contact with volatile sulfur compounds produced by decay-causing bacteria
A mouthguard that can detect the early signs of tooth decay and periodontitis has been developed by researchers from China. Made from a nanocomposite, the device reacts with the volatile sulfur compounds released by the bacteria that cause bad breath to highlight where dentists might need to make closer examinations.
