Which acid listed is associated with enamel demineralization in soft beverages?

• A. Acetic acid
• B. Phosphoric acid
• C. Formic acid
• D. Oxalic acid

Answer: (B)

Enamel demineralization happens when the mouth becomes acidic enough to dissolve the mineral that makes up tooth enamel. The critical pH for this process is about 5.5, so beverages that drop pH well below this threshold can cause mineral loss, especially with repeated exposure. Soft drinks commonly use phosphoric acid as an acidulant, which strongly lowers pH and remains present during sipping, making it the acid most often linked to enamel erosion in these beverages. While acetic, formic, and oxalic acids can contribute to enamel wear in other contexts, they are not the typical culprits in standard soft drinks. Therefore phosphoric acid is the acid most linked to enamel demineralization in soft beverages.
