Encyclopedia > Attrition (dental)

Attrition is the loss of tooth structure due to by mechanical forces from opposing teeth. Attrition initially affects the enamel and, if unchecked, may proceed to the underlying dentin. Once past the enamel, attrition quickly destroys the softer dentin. This does not cite its references or sources. ... Tooth enamel is the hardest and most highly mineralized substance of the body , and with dentin, cementum, and dental pulp is one of the four major parts of the tooth. ... Parts of a tooth, including dentin Dentin (BE: dentine) is the substance between the enamel (substance in the crown) or cementum (substance in the root) of a tooth and the pulp chamber. ... Parts of a tooth, including dentin Dentin (BE: dentine) is the substance between the enamel (substance in the crown) or cementum (substance in the root) of a tooth and the pulp chamber. ...


The most common cause of attrition is bruxism. Functional habits are those such as chewing and swallowing, which usually puts very little force on opposing teeth. Parafunctional habits, such as clenching and clicking the teeth together nervously, place greater amounts of forces on opposing teeth and begin to wear the teeth. As expected, wear usually begins on the incisal or occlusal surfaces. Bruxism (derived from Greek βρυγμός, masculine noun - grinding [teeth]) is grinding of the teeth. ... A para-functional habit or parafunctional habit is the habitual exercise of a body part in a way that is other than the most common use of that body part. ...
