Abfraction

Loss of tooth structure not caused by tooth decay

Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay. It is suggested that these lesions are caused by forces placed on the teeth during biting, eating, chewing and grinding; the enamel, especially at the cementoenamel junction (CEJ), undergoes large amounts of stress, causing micro fractures and tooth tissue loss. Abfraction appears to be a modern condition, with examples of non-carious cervical lesions in the archaeological record typically caused by other factors.
