The loss of tooth structure can be classified into two categories: loss occurring from disease or loss from a non-disease source. The majority of tooth structure loss from disease is a result of microbiological activity (caries). Non-disease-related tooth structure loss may be divided into the sub-categories attrition, abrasion, and erosion. Attrition is defined as the loss of tooth structure (enamel and dentin) resulting from tooth-to tooth contact. Tooth structure loss from abrasion is usually mechanical in nature, whereas, in the case of erosion, the loss of tooth structure is through chemical action. This article will focus on tooth structure loss by erosion—its etiology, diagnosis, and management.
