Which form of tooth surface loss is most commonly associated with bruxism?

Bruxism, which involves the habitual grinding or clenching of teeth, typically leads to the wear of the teeth over time. The most commonly associated form of tooth surface loss in these cases is attrition. This occurs as the opposing surfaces of the teeth grind against each other, resulting in the gradual wearing down of enamel and dentin.

When teeth grind together, the friction can lead to a flattened appearance of the chewing surfaces, often seen in those who grind their teeth during sleep or under stress. This mechanical wear is distinct from erosion, which results from chemical processes, or abfraction, which is a loss of tooth structure caused by flexural forces that lead to microfractures. Understanding the characteristics of attrition is crucial for dental health professionals in diagnosing and managing the effects of bruxism on patients' dental health.
