The impact of acidic foods and beverages on tooth enamel and how to minimize erosion.

Acidic foods and drinks, including citrus fruits, carbonated beverages, wine, and vinegar-based dressings, can directly erode tooth enamel. This chemical erosion differs from decay as it doesn't require bacteria. To minimize acid erosion: wait 30 minutes before brushing after acidic foods (brushing softened enamel causes more damage), use a straw for acidic drinks, and rinse with plain water after consumption.
