AInhibiting salivary amylase
BBlocking sugar uptake by oral bacteria
CEnhancing remineralization of early carious lesions
DDirectly killing cariogenic bacteria

✓ Correct answer: C. Enhancing remineralization of early carious lesions Fluoride primarily inhibits dental caries by enhancing remineralization of early carious lesions through the formation of fluorapatite, which is more resistant to acid dissolution than hydroxyapatite.
