What are environmental causes of tooth surface erosion?
Plaque is a sticky film made up of saliva, food particles, bacteria, and other substances. Plaque forms between your teeth and gets inside tiny holes or pits in the molars. It also gets around your fillings and next to the gum line where the teeth and gums meet. Sometimes the bacteria in plaque changes food starches into acids. When this happens, the acids in plaque start to eat away at the healthy minerals in the tooth enamel. This causes the enamel to wear down and become pitted. Over time, the pits in the enamel increase and grow in size.
