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.
Tooth wear refers to loss of tooth substance by means other than dental caries. [1] Tooth wear is a very common condition that occurs in approximately 97% of the population. [ 2 ] This is a normal physiological process occurring throughout life; but with increasing lifespan of individuals and increasing retention of teeth for life, the ...
Abfraction is a theoretical concept explaining a loss of tooth structure not caused by tooth decay (non-carious cervical lesions). 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 ...
Non-carious cervical lesions on an incisor belonging to Australopithecus africanus. Arrows show the location of the lesions. Non-carious cervical lesions (NCCLs) are a group of lesions that are characterised by a loss of hard dental tissue at the cementoenamel junction (CEJ) region at the neck of the tooth, without the action of microorganisms or inflammatory processes.

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 ...
Excessive tooth wear, [12] particularly attrition, which flattens the occlusal (biting) surface, but also possibly other types of tooth wear such as abfraction, where notches form around the neck of the teeth at the gumline. [15] Tooth fractures, [11] and repeated failure of dental restorations (fillings, crowns, etc.). [3]
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. [citation needed]
Any treatment necessary is mostly for patients with concerns on the appearance of the tooth. If they want to and are able to, they can get a crown or veneers . [ 13 ] Most patients can continue normally with enamel infractions as long as the infraction does not get bigger or cause any complications.
