Healthy Foods That Can Be Bad For Your Teeth

Some foods that are genuinely good for your overall health can actually damage your teeth when eaten too often. Here are a few particularly popular culprits. We’re not saying to avoid these foods completely, but you should know which ones to consume in moderation.


In case you didn’t know, it’s not sugar itself that causes tooth decay, it’s the acid that bacteria turns sugar into by digesting it. Acid is the enemy of tooth enamel. Lemon juice is quite acidic, so consuming it too often can actually weaken your enamel just like eating too much sugar. Lemons are rich in vitamin C. Without enough vitamin C in your diet, you can get scurvy, which ironically can cause your teeth to loosen and fall out. So, lemon is good for you in moderation, but try to avoid adding it to your water and sipping on it all day. You’d be giving your teeth a constant bath in cavity-causing acids!


Blueberries are known for being rich in antioxidants, vitamins and inflammation-fighting compounds. They’re also nature’s candy and totally delicious. But if you’ve ever dropped a fresh, juicy berry on light clothing, you also know that they create a pretty stubborn stain. What’s true of your favorite cotton shirt is also true of your tooth enamel. If you eat blueberries too frequently, you can contribute to staining and darkening your teeth. So if you’re trying to keep your smile bright after a teeth whitening treatment, we recommend limiting your blueberry intake. After all, the best teeth whitening is avoiding staining foods and drinks all together!

Carbonated Water

While not nearly as bad for your teeth as soda pop or carbonated energy drinks, carbonated water is not without guilt when it comes to tooth health. All carbonated drinks, including popular sugar-free, calorie-free flavor-infused waters, contain acid created by the carbonation process. All those fun fizzy little bubbles can actually damage your teeth over time if you drink too many carbonated drinks.
