Dental attrition is a type of tooth wear caused by tooth-to-tooth contact, [1] resulting in loss of tooth tissue, usually starting at the incisal or occlusal surfaces. Tooth wear is a physiological process and is commonly seen as a normal part of aging.
The word attrition is derived from the Latin verb attritium, which refers to the action of rubbing against something. [2] Attrition mostly causes wear of the incisal and occlusal surfaces of the teeth. Attrition has been associated with masticatory force and parafunctional activity [2] such as bruxism. A degree of attrition is normal ...

Overerupted teeth are often sharp due to lack of tooth wear (dental attrition) by adjacent teeth during chewing. [ citation needed ] Overeruption is treated either by forcing the tooth back using orthodontic techniques, or by cutting the interfering part of the tooth and installing a crown .
The aetiology of dental abrasion can be due to a single stimulus or, as in most cases, multi-factorial. [6] The most common cause of dental abrasion is the combination of mechanical and chemical wear. Tooth brushing is the most common cause of dental abrasion, which is found to develop along the gingival margin, due to vigorous brushing in this ...
