When you eat foods such as chips, pasta, breads and crackers, the bacteria in your mouth digest these carbohydrates and turn them into acid. The acid causes tooth decay.
American Dental Association answered
Tooth erosion is a condition that occurs when acids eat away at a tooth’s surface. If you eat too many unrefined carbohydrates you are exposing your teeth to extra and unnecessary sugars, which can lead to decay and erosion. You can improve your oral health and avoid tooth erosion by drinking lots of water and brushing your teeth two times a day for two minutes with a fluoride toothpaste and by flossing daily.
