caption_attribution_description: English: Non-carious cervical lesions on an incisor belonging to Australopithecus africanus. Arrows show the location of the lesions.
context_page_description: Non-carious cervical lesions are defined as dental tissue lost at or near the cementoenamel junction, and not relating to tooth decay. NCCLs are common in the dentitions of recent human populations. They may result from several processes including abrasion, acid erosion and abfraction. It is thought recent changes in diet and behaviour may explain the high rate of NCCLs in humans today, including consuming a lot of acidic foods and drinks, as well as tooth brushing techniques. Periodontal disease is often also a contributing factor.
