Sugar-free foods may be less likely to cause tooth decay, but these foods can still cause tooth erosion. Tooth erosion is a type of tooth wear. It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids. In other words, tooth erosion can be caused by acidic flavouring and preservatives added to sugar-free foods. The harm caused by this is irreversible and can dissolve your teeth over time.
