Description

This anatomical visualization illustrates abfraction lesions, which are seen as wedge-shaped notches near the cervical areas of the teeth, particularly on the buccal surfaces of the premolars and molars. These defects are not caused by decay but result from biomechanical forces such as bruxism or occlusal stress that cause the enamel and dentin to flex and fracture away from the cervical region. The image clearly depicts how these non-carious cervical lesions appear below the enamel–cementum junction, often accompanied by gingival recession. This condition can lead to sensitivity, especially when exposed dentin reacts to temperature changes or acidic foods.
