Polish Journal of Public Health, 2014 Dental erosion is described as an irreversible loss of dental hard tissue resulting from exposure to non-bacterial acids or chelating substances. It may be caused by exogenous or endogenous factors. In the former case, food, drink, as well as the environment might be sources of acids; in the latter, acids flowing into the oral cavity from the stomach ...
