Tooth (dental) erosion:
Tooth erosion is a common problem. It is the gradual erosion of tooth enamel by the action of acid on the teeth. This is different to damage caused by bacteria resulting in tooth decay and caries. Tooth erosion affects the entire surface of the tooth. In time, tooth erosion can cause thinned enamel, and eventually can expose the softer dentine underneath the enamel. Dentine is sensitive so erosion can lead to your teeth being more sensitive to hot, cold or sweet foods and drinks.
