Dental attrition is tooth wear caused by tooth to tooth contact. Well-defined wear facets appear on tooth cusps or ridges. This can be caused by several factors, including parafunctional habits such as bruxism or clenching, developmental defects, hard or rough-textured diet, and absence of posterior teeth support.
Bruxism is excessive teeth grinding or jaw clenching. It is an oral parafunctional activity; [1] i.e., it is unrelated to normal function such as eating or talking. Bruxism is a common behavior; the global prevalence of bruxism (both sleep and awake) is 22.22%. [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, especially in elderly individuals. [10]
Bruxism, also known as clenching of or grinding on teeth, destroys enamel very quickly. The wear rate of enamel, called attrition, is 8 micrometers a year from normal factors. [citation needed] A common misconception is that enamel wears away mostly from chewing, but actually teeth rarely touch during chewing.
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. In dentistry, orthodontics, and oral and maxillofacial pathology, the body part in question is usually the mouth, tongue, or jaw.

This article was the first to establish abfraction as a new form of lesion, differing from abrasion, attrition, and erosion. [ 2 ] Tooth tissue is gradually weakened causing tissue loss through fracture and chipping or successively worn away leaving a non-carious lesion on the tooth surface.
The high dropout rates have provoked neither an internal crisis nor a re-evaluation of programming. Stamper dismissed dropouts as “attrition by personal choice.” An addict’s failure is considered a result of not being ready for treatment, never an indication that there might be a problem with the treatment itself.
