Zahnabrieb

Zahnabrieb, also known as tooth wear, is the progressive loss of tooth structure due to factors other than dental caries or trauma. It is a common condition that can affect teeth throughout a person's life. Zahnabrieb can manifest in several ways, including attrition, abrasion, erosion, and abfraction.

Attrition refers to the wear that occurs from tooth-to-tooth contact, typically seen in bruxism (teeth grinding) or clenching. Abrasion is the loss of tooth structure caused by external mechanical forces, such as aggressive toothbrushing with an abrasive toothpaste or habitual use of toothpicks. Erosion is the dissolution of tooth structure by chemical or acidic agents, which can originate from intrinsic sources like stomach acid (e.g., in cases of bulimia or acid reflux) or extrinsic sources like acidic foods and beverages. Abfraction involves loss of tooth structure at the cervical area of the tooth, often attributed to occlusal stresses that create tensile and compressive forces.

The effects of Zahnabrieb can range from mild aesthetic concerns to significant functional problems. Tooth sensitivity, changes in tooth shape and length, and increased risk of fracture are potential consequences. Diagnosis typically involves a clinical examination by a dental professional, who will assess the pattern and severity of tooth wear. Treatment strategies are aimed at addressing the underlying cause and restoring lost tooth structure if necessary. Preventive measures include modifying habits, using protective appliances like night guards for bruxism, and adopting proper oral hygiene techniques.
