What is the role of acid in damaging tooth enamel?
Answer and explanation
Correct answer: Acid can help dissolve enamel
Tooth enamel is a hard mineral layer, mainly containing calcium phosphate. Bacteria in dental plaque use sugars and produce acids. When the pH at the enamel surface falls sufficiently, the mineral dissolves more readily; repeated demineralisation can produce cavities. Thus acid promotes enamel erosion and tooth decay, making option A correct. It does not turn enamel into gold, strengthen it, or lack any connection with dental damage.
