Frequent exposure to soft drinks—whose pH typically ranges from 2.7 to 3.5—drives enamel demineralization because enamel begins to dissolve at pH 5.5 and below. Phosphoric acid (in colas) and citric acid (in fruit-flavored sodas) chelate calcium and phosphate ions from hydroxyapatite crystals, weakening the enamel’s structure. Over time, this erosion not only roughens the tooth surface but also predisposes the dentin to further decay and sensitivity . Regular, prolonged consumption without adequate remineralization from saliva or fluoride can lead to irreversible loss of tooth tissue and increased risk of cavities.
