クエン酸
Acid erosion is defined as the loss of tooth enamel caused by acid attack. When consuming carbonated sugar sweetened beverages, acid deposits on the teeth, attacking the enamel. Over a gradual period, the enamel is worn down, which can lead to dental caries. Erosion of tooth enamel begins at a pH of 5.5, and ingredients found in sugar sweetened beverages such as phosphoric acid and citric acid significantly contribute to the demineralization of the enamel. Citric acid in various sugar sweetened beverages can cause chelation.
