Acidic oral compositions having reduced tooth erosion characteristics, especially
acid beverages such as fruit juice drink concentrates, or oral healthcare products
such as mouthwashes, are prepared by adding a calcium compound to the acid composition
so that the mol ratio of calcium to acid ranges from 0.3 to 0.8, and the pH of
the composition, if necessary after adjustment with an alkali, is from 3.5 to 4.5.
