Natural Sources of Fluoride

Natural Sources of Fluoride

Dentists talk a lot about fluoride, and for good reason! Fluoride is a mineral that has been shown to strengthen teeth, prevent cavities and reduce sensitivity. Fluoride is added into many city water supplies for this very reason. It’s also added to toothpastes, mouthwashes and floss. But did you know that fluoride also naturally occurs in many foods and drinks? Let’s talk about natural sources of fluoride and how to make sure you’re getting an adequate amount to fight cavities.


Seafood like crab legs and shrimp are not only a delicious and fancy delicacy, but also among the best natural sources of fluoride.

Wine, Juice, Grapes and Raisins

Grapes contain fluoride, no matter how you toss them, sun them, or squeeze them. Raisins are one of the most concentrated sources of natural fluoride, but they can also contain a lot of extra sugar that can be bad for your teeth. White wine contains twice as much fluoride as red wine, so the amount of fluoride can vary quite a bit depending on the source, but however you choose to enjoy grapes, you’ll be adding natural fluoride to your diet and that’s a good thing!


Many kinds of fresh fruit are excellent natural sources of fluoride, just be sure to eat the fruit raw. Fruit that contains fluoride includes apples, peaches, strawberries, bananas, watermelon, cherries and countless others.


Potatoes are a great source of fluoride because, like grapes, there are so many different ways you can enjoy them! Russet potatoes have the highest amount of fluoride, but any variety will provide you with some fluoride.

Coffee and Black Tea

Coffee and black tea both contain fluoride naturally, and if your city’s water supply contains added fluoride, you can get double the dose of fluoride in your drink just by brewing with tap water!

Talking to Your Dentist About Fluoride

If you’re looking for ways to strengthen your teeth and fight cavities, talk to your dentist about fluoride and the best ways to add it to your diet and routine. Your dentist may also suggest a concentrated fluoride treatment that can be applied after a cleaning to help give you a head start on ensuring your teeth absorb a sufficient amount of fluoride to protect and strengthen your teeth.
