Worried about the fluoride in your toothpaste or in the water you drink? There are many myths surrounding fluoride. A lot of these myths come from misinformation on the Internet. Here are the three most popular fluoride use myths and the real facts behind them. Be sure to continue brushing your teeth twice a day to maintain healthy teeth and gums.

Myth #1: It’s Unnatural

One of the most common myths, many patients might question their dentist about whether or not fluoride is natural and won’t harm them should they utilize it. Some patients will even ask if fluoride use will cause cancer due to prolonged, unnatural exposure. Patients can breathe a sigh of relief knowing that the National Cancer Institute asserts that there is no link between fluoride causing bone cancer in humans. This assertion is made citing surveys conducted by the Public Health Service and other national organizations. In addition, the American Dental Hygienists’ Association states that fluoride is found in small amount naturally in our water.  It has also been proven the fluoride helps to harden the enamel on teeth, which can lower the risk of dental cavities.

Myth #2: Fluoride Causes Thyroid Problems

If you’ve developed a thyroid issue, you might think that the fluoride in your toothpaste is to blame. The studies conducted in 2015 by the Epidemiology & Community Health helped give birth to this myth. According to the study, high levels of fluoride seemed to share a connection with hypothyroidism. What the study failed to do was make a causal link between the two, so it’s hard to say that fluoride use causes thyroid problems. In addition, another study found that subject who had fluorosis due to fluoride overexposure had normal thyroid levels.

Myth #3: Fluoride Is Toxic to Kids

Not only is fluoride safe for children, it also helps strengthen enamel in their teeth at an early age. If you are a parent concerned about your child’s dental health, ensure that your child is drinking fluoridated water with recommended levels of fluoride. Children should brush their teeth twice a day with tooth paste that contains fluoride as well. Brushing their teeth will also fight tooth decay and cavities. It is recommended, however, to be aware of the amount of fluoride your child is using. High levels of fluoride can cause fluorosis in children. Infants are susceptible as well, especially if parents mix infant formula that has fluoride and fluoridated water. To avoid this, mix baby formula with distilled or purified water.
