A sports drink is a beverage designed to help athletes rehydrate, as well as restore electrolytes, carbohydrates, and other nutrients, which can be depleted after training or competition. Electrolyte and carbohydrate replacement promotes proper rehydration and energy production, which is important in delaying the onset of fatigue during exercise and helps in better sport performance. Sports drinks commonly contain phosphoric acid, citric acid, certain additives and organic acids that can advance dental erosion. All acids have an erosive potential but the method of drinking will influence whether or not those acids affect the teeth. The purpose of this paper is to highlight the effects of sports drinks on tooth, which results in tooth erosion.
