The loss of tooth structure caused by the process of chemical dissolution and mechanical abrasion is becoming a great problem in modern dentistry. Patient awareness as well as diagnostic alertness of a dentist are crucial for proper prevention and treatment. Late diagnosis and treatment of extensive loss of tooth structure caused by erosion, abrasion or abfraction poses many difficulties for clinicians. Chronically progressive loss of tooth structure can cause loss of vertical dimension of the bite, secondary orthodontic complications and also aesthetic and functional problems. The treatment is often associated with long‑term diagnosis and interdisciplinary, expensive rehabilitation of the entire stomatognathic system. The aim of this study was to review current publications on the prevalence of tooth wear in developmental age, with focus on etiology, risk factors, prevention and treatment methods

Key words: non‑carious loss of tooth structure, children, developmental age, risk factors.
