Fluoride treatment is often praised for strengthening tooth enamel and helping to prevent cavities. Many people receive a fluoride treatment to help keep their oral health pristine and their smile bright. However, you might be unaware that certain foods can prevent fluoride from doing its job. Although fluoride treatment is very powerful in its teeth-saving capabilities, understanding the way food affects fluoride can help you keep its benefits longer.

In this blog, we will discuss five surprising foods that are hindering your fluoride intake. Whether you’re enjoying a meal with friends at a restaurant or after exploring stunning views, it’s important to understand how your food impacts the benefits of fluoride. 

By making a few easy changes, you can save your teeth and keep your fluoride treatment working for you. Read on to see what is interfering with your fluoride.

1. Sugary Snacks and Drinks

You likely already know that sugar contributes to cavities, but even more surprising is that sugar hinders fluoride. The reason is that the bacteria in your mouth feed on sugary foods and drinks, releasing acids that directly attack your enamel. This is the opposite of what fluoride does for your enamel. While fluoride helps remineralize your teeth, regularly consuming sugar overwhelms your enamel’s natural healing process.

Cookies, candies, and sugary drinks are all foods that weaken your enamel, leaving it unable to absorb fluoride and perform its function. If you’re snacking on such treats with friends even after receiving fluoride treatment in Medicine Hat, AB, be sure to rinse your mouth afterward, or stick with a healthier option.

2. Acidic Foods

Foods that contain high levels of acid, such as oranges, lemons, and vinegar, have been known to weaken your enamel and, therefore, leave your enamel less able to absorb the fluoride that you may have had recently. While these foods are generally healthy, their acidity can temporarily soften the enamel, making it less able to absorb fluoride properly. In the long run, the fluoride may never properly reach your enamel and work the way it needs to.

Drinking orange juice in the morning can be a refreshing way to kick off your day in Riverside. Still, after a morning cup of vitamin C, your enamel will not effectively absorb fluoride. To avoid this, wait at least 30 minutes after consuming acidic foods before brushing or applying fluoride treatments.

3. Dairy Products

Milk, cheese, and yogurt are known to contain a good amount of calcium, and calcium is the building block for strong teeth and bones. Unfortunately, while dairy products may be beneficial for your health, they can interfere with fluoride’s ability to reach your enamel. Calcium binds with fluoride, reducing its effectiveness in remineralizing teeth.

Calcium-rich foods are vital for strong bones, but it’s in your best interest to try to have your fluoride treatment in Medicine Hat, AB, and avoid dairy products for a while so that it has a chance to bind to your teeth properly. Whether you are enjoying coffee with milk at a local coffee shop or having cheese and wine downtown, give your enamel enough time to take in fluoride.

4. Tea and Coffee

Although these are two extremely popular choices in Medicine Hat and its surrounding communities, tea and coffee can stain teeth and reduce the effectiveness of a fluoride treatment. Tannins in both coffee and tea can bind to fluoride, thereby preventing it from bond to tooth enamel. Stains left by these drinks also prevent fluoride from properly binding to enamel.

It’s perfectly okay to have your cup of coffee or tea in the morning, just wait a bit longer after fluoride treatment. Brush your teeth, then rinse with water afterward so you do not inhibit the fluoride’s binding action and cause a negative interaction with the treatment.

5. Processed Foods and Starchy Foods

Processed foods and starchy foods (like chips, crackers, and white bread) contribute to a very negative oral environment regarding fluoride treatment. These foods are easily digested into sugars, which help feed bacteria in the mouth. Bacteria produce acids that erode enamel, making fluoride treatments less effective. Also, processed foods tend to be nutrient-poor and promote natural enamel regeneration.

When you reach for a chip or snack at Medicine Hat’s Kin Coulee Park, or when you’re enjoying lunch, be mindful of how food interacts with your fluoride treatment. Choose fruits, vegetables, and whole grains whenever you can.

Conclusion: The Way To Most Effectively Use Your Fluoride Treatment

By following these guidelines and limiting your intake of foods that can interfere with a fluoride treatment’s ability to protect your enamel properly, you will maximize the treatment’s protective and regenerative benefits. The main thing to remember is to eat these foods moderately and to give your fluoride treatment in Medicine Hat, AB, some time to bond properly before consuming them.
