Coloured SEM of dental plaque seen on a tooth
Tooth plaque (Second of four images). Coloured scanning electron micrograph (SEM) of plaque on the surface of a tooth. Plaque,the main cause of tooth decay,appears as a yellow coating over the grey enamel of the tooth. Plaque is a sticky substance made of food remains and the bacteria that naturally occur in the mouth (such a Strepto- cocci). Bacteria feed on the sugars in the food particles and produce acid as a waste product. This acid corrodes the enamel coating of each tooth,forming cavities and exposing the pain receptors in the tooth's sensitive interior. Magnification: x270 at 6x6cm size.
