Citrus fruits—including lemons, oranges, and grapefruits—must be approached with caution. Despite their well-known benefits from high vitamin C and antioxidant content, their intense acidity can lead to enamel erosion. While it's unnecessary to eliminate them entirely, consuming them frequently as a stand-alone snack or slowly sipping their concentrated juices can be highly erosive. It is recommended to consume them as part of a meal and rinse the mouth with water immediately afterward to help neutralize the acid.
