Since the 1940s, an array of products containing fluoride have been introduced to the average consumer. These sources of fluoride exposure can contribute to human health risks.
Some products that may contain added fluoride and contribute to human health risks include the following:
|Artificially fluoridated municipal water||Beverages (made with fluoridated water)|
|Dental cements with fluoride||Dental fillings with fluoride|
|Dental gels with fluoride||Dental varnishes with fluoride|
|Floss with fluoride||Fluoride drugs (“supplements”)|
|Food (that contains or has been exposed to fluoride)||Mouthwash with fluoride|
|Pesticides with fluoride||Pharmaceutical drugs with perfluorinated compounds|
|Stain resistant and waterproof items with PFCs||Toothpaste with fluoride|
The potential health risks generated from exposure to these sources of fluoride are often overlooked. Additionally, age, gender, genetic factors, nutritional status, weight, and other factors are known to influence each person’s unique reaction to fluoride. For example, children’s exposure to fluoride is extremely important to consider, and this issue was made evident in recent news about a study linking fluoride exposure in utero with lower IQs. As another example, fluoride was recently identified as one of 12 industrial chemicals known to cause developmental neurotoxicity in humans.
This chart includes some of the specific human health risks associated with fluoride exposure:
|Acne and other dermatological conditions||Arterial calcification
|Bone weakness and risk of fractures||Cancer of the bone, osteosarcoma|
|Cardiac failure||Cardiac insufficiency|
|Cognitive deficits||Dental fluorosis|
|Diabetes||Early puberty in girls|
|Electrocardiogram abnormalities||Harm to the fetal brain|
|Hypertension||Immune system complications|
|Lower fertility rates||Lower IQ|
|Myocardial damage||Neurotoxic effects, including ADHD|
|Temporomandibular joint disorder (TMJ)||Thyroid dysfunction|

Exposure to excess fluoride can result in dental fluorosis, a condition in which the teeth enamel becomes irreversibly damaged. Additionally, the teeth become permanently discolored, displaying a white or brown mottling pattern and forming brittle teeth that break and stain easily.
Dental fluorosis is recognized as the first visible sign of fluoride toxicity. It is likewise a warning signal of the human health risks associated with fluoride exposure. According to 2010 data from the Centers for Disease Control and Prevention (CDC), 23% of Americans aged 6-49 and 41% of children aged 12-15 exhibit fluorosis to some degree. An assessment of the CDC’s data further demonstrates that 58% of children aged 6-19 have fluorosis.
Increased sources of fluoride exposure are accompanied by increased human health risks. Therefore, it has become a necessity to reduce and work toward eliminating avoidable sources of fluoride exposure, including water fluoridation, fluoride-containing dental materials, and other fluoridated products.
