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.

Lemon

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

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.

Detox water (also known as skinny water) is promoted as a great all natural way to cleanse the body and lose weight. These do-it-yourself fruit and herb infused water concoctions are supposed to be great for your overall health, but there’s one problem: detox water can be really bad for your teeth!

Perhaps the most common ingredient in detox water recipes is lemons, though other citrus fruits such as limes, grapefruit, and oranges also make an appearance. Citrus fruits are acidic: they contain citric acid. However, what you might not know is that lots of other fruits are highly acidic too, including pineapples, mangoes, peaches, pomegranates and even blueberries. Some recipes even call for apple cider vinegar, which is also acidic.

Acid is one of your smile’s greatest enemies. Acids can eat through the hard outer enamel layer of your teeth, causing spots, cavities, and a great place for tooth decay-causing bacteria to start an infection. (Fun fact: It’s actually acid that links sugar to tooth decay. The existing bacteria in your mouth consume the sugar and excrete acid as a byproduct, right onto your teeth. Lovely, right?)

So, it turns out, depending on the ingredients, detox water is a nice tasty erosion-causing acid bath for your teeth. Okay, that may be a little dramatic, but detox water certainly puts your teeth at higher risk for tooth decay than plain clean water.

The truth is, detox water (like most flavored drinks) are fine in moderation. Unfortunately, moderation is not what a lot of detox water lovers recommend. A lot of instructions for detox water suggest sipping it all day long. That means repeatedly subjecting your teeth to an acidic environment!

Drinking detox water is okay, and will probably benefit your health by keeping your better hydrated (other health claims are dubious, but that’s another story). Your dentist just asks you to be sensible about it. Just like we recommend not snacking between meals, we also suggest not drinking detox water between meals. This will give your teeth “time off” from being covered in acids, sugars, etc. Most dentists will tell you that the only thing you should be sipping on all day is water. Consider drinking a detox water with breakfast, then brushing your teeth and going about your day with a fun, well-designed bottle of fruit-free water instead.

If you have a detox water habit you just can’t shake, there are some steps you can take to reduce its impact on your teeth. One way is to use a straw, which helps keep the liquid from hitting your teeth directly. You can also flush your mouth with plain water every time you drink the detox water, to help wash away the acid and any sugars. However, remember that the primary way that detox water “draws out toxins” and improves your health is by encouraging you to consume more water. When it doubt, regular fluoridated tap water is your smile’s best friend.
