Non-carious cervical lesions (NCCLs) are structural defects caused by combined mechanical, chemical, and biomechanical stress in the cervical region of the tooth. Accurate diagnosis is essential and requires careful clinical examination, patient history, and modern diagnostic tools to distinguish them from carious lesions and detect early changes. Management focuses primarily on preserving natural tooth structure through preventive strategies and behavioral modification, such as correcting brushing habits, reducing dietary acids, and managing occlusal stress. Minimally invasive approaches are preferred, while restorative treatment is indicated only when hypersensitivity, aesthetic concerns, or structural compromise occur. The use of advanced adhesive systems and bioactive materials supports a biomimetic treatment approach. Long-term success depends on patient compliance, risk factor control, and regular follow-up care.
