The Causes of Acid Erosion

Having an acid-rich diet can put our teeth at risk. As few as four acidic "occasions" throughout the day can put your enamel at risk from acid erosion, also known as acid wear.

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

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

What is pH and how is it measured?

pH is a measure of how acidic (pH < 7) or alkaline (pH > 7 but less than 14) something is. For people concerned about an acidic diet and acid erosion, the most important thing to know is this: the lower the pH number, the more acidic a food or a drink is and the more harmful it is to your tooth enamel.

For example, distilled water has a neutral pH of 7, while tomato juice might have a pH of 4 and lemon juice might have a pH of 2—making the lemon juice the most acidic of the three.

Knowing the pH value of the foods we eat and the beverages we drink helps us have a clearer picture of how acidic our diet really is. And knowing the acidity of our diet is an important step in making sure we protect our tooth enamel from acid erosion.
