Tooth plaque. Coloured scanning electron micrograph (SEM) of dental plaque on a human tooth. Plaque is the main cause of tooth decay. It consists of saliva,bacteria and food debris. The bacteria feed on the sugars in food,producing acid as a waste product. This acid corrodes the enamel coating of each tooth,resulting in tooth decay (dental caries).
