Acid erosion is a type of tooth wear. It is defined as the irreversible loss of tooth structure due to chemical dissolution by acids not of bacterial origin.[1] Dental erosion is the most common chronic condition of children ages 5–17,[2] although it is only relatively recently that it has been recognised as a dental health problem.[3] There is widespread ignorance of the damaging effects of acid erosion; this is particularly the case with erosion due to consumption of fruit juices because they tend to be seen as healthy.[4] Acid erosion begins initially in the enamel, causing it to become thin, and can progress into dentin, giving the tooth a dull yellow appearance and leading to dentin hypersensitivity.[5]
The most common causes of erosion are acidic foods and drinks. In general, foods and drinks with a pH below 5.0–5.7 have been known to trigger dental erosion effects.[6] Numerous clinical and laboratory reports link erosion to excessive consumption of such drinks. Those thought to pose a risk are soft drinks, some alcohol and fruit drinks, fruit juices such as orange juice (which contain citric acid) and carbonated drinks such as colas (in which the carbonic acid is not the cause of erosion, but citric and phosphoric acid).[7] Additionally, wine has been shown to erode teeth, with the pH of wine as low as 3.0–3.8.[6] Other possible sources of erosive acids are from exposure to poorly regulated chlorinatedswimming pool water,[8] and regurgitation of gastric acids.[9] In children with chronic diseases, the use of medicines with acid components is a risk factor too.[10] Dental erosion has also been recorded in the fossil record and was likely caused by the consumption of acidic fruits or plants.[1]
