Citric Acid Is In Your Body, Food, Skincare, and Medicine

9. Citric Acid and Tooth Erosion

Citric acid in foods and beverages can wear away the enamel on the teeth, causing permanent tooth erosion. To avoid this, eat foods high in citric acid along with less acidic foods such as cheese, nuts, or brown rice. After consuming such foods, rinse the mouth with water. Wait an hour before brushing teeth to allow saliva to wash away the acid naturally.

Many experts encourage people to avoid holding beverages high in citric acid in their mouths. Using a straw or swallowing promptly is best.
