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. Multiple factors are seen as contributing to the development of noncarious cervical lesions (NCCLs). The term abfraction is applied to these lesions in relation to. Evidence supports that abfraction lesions, as any NCCLs, have a multifactorial etiology. Particularly, the cervical wear of abfraction can occur.

In cases of asymptomatic teeth, where tooth vitality and function are not compromised, abfraction lesions should be monitored for at least 6 months before any invasive procedure is planned.

Abfraction lesions: etiology, diagnosis, and treatment options

Particularly, the cervical wear of abfraction can occur as a result of normal and abnormal tooth function and may also be accompanied by pathological wear, such as abrasion and erosion. Other factors can contribute to tooth loss, however. When looking at abfraction lesions there are generally three shapes in which they appear, appearing as either wedge, saucer or mixed patterns.

On the longevity of teeth. Erosion processes are often associated with the diagnosis of abfraction lesions. Prosthetic restorations may be necessary to restore abfraction lesions in teeth that are planned as an abutment for a removable partial denture. Not all chewing and biting is believed to lead to abfraction.

The clinical decision to restore abfraction lesions may be based on the need to replace form and function or to relieve hypersensitivity of severely compromised teeth or for esthetic reasons. Clinical strategies based on scientific evidence and clinical experience.

If you do not seek treatment for the cause of your abfractions as well as the lesions themselves, the damage will continue. More Videos You May Like. Dietary erosion occurs due to high consumption of foods or drinks containing a variety of acids, such as those from citrus and other fruits, fruit juices citric acidsoft drinks, wine, and other carbonated drinks carbonic acid and other acids.


As previously suggested, if abfraction is suspected to be a dominant factor in the etiology of NCCLs, then any decision to carry out destructive, irreversible treatment, such as occlusal adjustment, should be considered very abfractioh. It is apparent in clinical practice that not all patients with abfraction lesions present occlusal wear bruxism or clenchingand not all patients with occlusal wear exhibit NCCLs.


If there are concerns around aesthetics or clinical consequences such as dentinal hypersensitivitya dental restoration white filling may be a suitable treatment option. Being theoretical in nature there is more than one idea on how abfraction presents clinically in the mouth. Clinical assessment of non carious cervical lesion using swept-source optical coherence tomography.

Thus, one must conduct a risk-benefit analysis when considering restorative treatment of abfraction lesions. Abfraction lesions will generally occur in the region on the tooth where the abfractioon tensile stress is located.

Causes of Abfraction – South Ogden, UT

Abfraction lesions are more prevalent in the adult age population of 40 years old affecting mainly the premolar teeth. In order to avoid and control inappropriate occlusal forces, night guard devices has been advised to minimize the initiation of NCCLs. In addition to the temporomandibular joint TMJ pain the condition can cause, patients may also suffer tooth loss in the form of abfractions.


The major reasoning behind the controversy is the similarity of abfraction to other non carious lesions and the prevalence of multiple theories to potentially explain the lesion. It is expected that the chronic nature of abfraction, which is accompanied by the natural process of dentinal remineralization, will lesiins relieve tooth sensitivity.

Abvraction changes to tooth crowns.

Another important factor deserving attention while planning for the restoration of abfraction lesions is the restoration retention. Find Out Which Treatment Is Right for You Treating the underlying causes of abfraction can help improve oral health and prevent damage caused by abfraction lesions.

An abfraction is a condition in which small notches, or lesions, develop near the gum line. Other treatment options include the following: Non-carious changes to tooth crowns. As a result of the reported associations between occlusal stress and abfraction lesions, occlusal adjustment has been proposed as an alternative treatment to prevent the initiation and progression of these lesions and to minimize failure of cervical restorations.

One of the most prevalent theories is called “the theory of non-carious cervical lesions” which suggests that tooth flexion, occurring due to occlusion factors, impacts on the vulnerable area near the cementoenamel junction. Hammadeh M, Rees JS.
