Dental Erosion from Abrasion & Abfraction

What is dental abrasion? Unlike dental attrition, abrasion is the loss of tooth structure by mechanical forces from a foreign element. If this force begins at the cementoenamel junction, then the progression of tooth loss can be rapid since enamel is thin in this region of the tooth. Once past the enamel, abrasion quickly destroys the softer dentin and cementum structures. The appearance is commonly described as V-shaped when caused ...

A Picture of Dental Attrition of the Teeth

What is dental attrition?

What is dental attrition? The definition of dental attrition is the mechanical wearing of the incisal or occlusal surfaces of teeth as a direct result of functional or parafunctional tooth-to-tooth contact. The process is usually slow and rarely results in pulpal disease as secondary dentine is laid down to protect the pulp. Tooth pain is rarely associated with attrition, and men typically show a greater degree of attrition than women ...

What is Tooth Erosion? Causes, Diagnosis, and Treatment

What is tooth erosion? Erosion is the wearing away of the tooth surface by an acid, which dissolves the enamel and the dentine. There are a variety of ways that tooth structure is lost. Food-based dental erosion was first described in 1892 among Sicilian lemon pickers. Food and beverages can dissolve tooth structure if they are acidic enough. Gastric regurgitation is another source of acid that can dissolve teeth. Exposure ...
