List of Foods That Naturally Contain Fluoride

Fluoride is crucial for maintaining dental health, as it strengthens your tooth enamel and makes it more resistant to decay and cavities. While most people associate fluoride with dental treatments and toothpaste, it’s also worth knowing that certain foods can contain fluoride naturally. At Birch Point Dental Clinic, we are committed to supporting your oral health journey, and so we’re here to provide a list of fluoride-rich foods that will help you care for your enamel and keep your teeth healthy. 

Naturally, Fluoride-Rich Foods To Include In Your Diet

Fluoride offers many benefits to your oral health. It strengthens your tooth enamel, which helps prevent decay, alleviates tooth sensitivity, and even reverses the early signs of tooth decay known as demineralization. So, why not include it in your diet with delicious, healthy foods? Here are some excellent food options that naturally contain fluoride: 

  • Grapes: Black and red grapes naturally contain fluoride due to their exposure to the soil. As a nutritious snack that contains vitamins such as B, C, and K, grapes can be a great addition to your diet. 
  • Spinach: Spinach is considered a superfood in terms of how many vitamins and minerals you receive, including vitamins C, K, iron, and potassium. However, you also receive fluoride from spinach, making it an excellent food choice for your teeth. Adding spinach to your salads, smoothies, and other dishes can be a great choice for your health. 
  • Tea: Drinking tea, such as green or black tea, can give you a boost to your fluoride content, as it naturally absorbs fluoride from the soil. Drinking tea can be a great way to increase your fluoride intake, but limiting your consumption is recommended if you suffer from tooth discoloration. 
  • Apples: Apples, especially the outer skins of the apples, also contain fluoride! These nutritious fruits are packed full of vitamins such as riboflavin, thiamin, and B6 and contain healthy fiber that assists with saliva production for your teeth. Just make sure to eat the skins of the apple for maximum benefits!
  • Fish: Certain types of fish, such as canned sardines and salmon, are great sources of fluoride because fluoride naturally accumulates in their bones as these fish grow and develop. Including these fish in your diet can significantly boost your fluoride intake.
  • Potatoes: Potatoes, especially when consumed with their skins, contain small amounts of fluoride. Since the skin of potatoes holds fluoride, try baking or roasting them with the skins intact to take advantage of their nutritional value.
