Foods and Drinks That Cause Acid Erosion

Having an acid-rich diet can put your tooth enamel at risk of acid erosion. As few as four acidic occasions throughout the day is all it takes.

What counts toward those occasions? Surprisingly, some of our healthier choices—like fruit, fruit juices, sparkling water with lemon, and even salad dressings—in addition to wine and soda are highly acidic.

Here are some common acidic foods and drinks that you might encounter on a daily basis.
