Acid erosion, also known as dental erosion, is the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin. Dental erosion is the most common chronic disease of children ages 5–17, although it is only relatively recently that it has been recognised as a dental health problem.

This is then followed by purging, which are efforts to lose weight such as self-induced vomiting, long hours of excessive exercise, taking laxatives and diuretics. The most common method is self-induced vomiting, which is done by sticking a finger down the throat following an episode of over-eating so that food is vomited out before it is absorbed by the body.
