The 7 Worst Foods For Your Teeth

5. Citrus

Oranges, grapefruits, and lemons are tasty as both fruits and juices, and are packed with vitamin C. But their acid content can erode enamel, making teeth more vulnerable to decay. Even squeezing a lemon or lime into water adds acid to a drink. Plus, acid from citrus can be bothersome to mouth sores. If you want to get a dose of their antioxidants and vitamins, eat and drink them in moderation at mealtime and rinse with water afterward.
