Dental erosion (DE), defined as a pathological, chronic and irreversible dissolution of dental hard tissues caused by acids of a non-bacterial origin, 1 has been identified as a globally emerging oral health problem. 2 The estimated global prevalence of DE is 30% in adolescents, 25% in Australia. 3 Understanding of risk factors and early diagnosis are essential to prevent and manage DE. 4 When allowed to progress, it can lead to dentinal hypersensitivity, aesthetic concerns and loss of vertical dimension, all of which affect oral health-related quality of life. 3,5 Management of advanced DE often requires costly and invasive functional and aesthetic rehabilitation. 6 DE is multifactorial and is caused by a complex interaction between environmental factors and tooth enamel. 7 Dietary acids are not only considered the predominant factor, but also the easiest to control. 8-10 Such acids can arise from a number of sources including soft drinks, sports/energy
