Referring to a common salt of fluoride, sodium fluoride (NaF), the lethal dose for most adult humans is estimated at 5 to 10 g (which is equivalent to 32 to 64 mg elemental fluoride/kg body weight). [ 2 ] [ 3 ] [ 4 ] Ingestion of fluoride can produce gastrointestinal discomfort at doses at least 15 to 20 times lower (0.2–0.3 mg/kg or 10 to 15 ...
However, too much fluoride can cause fluorosis, "which presents as white streaks or blotchy white patches on the enamel," Kosdon says. "These chalky areas are known as decalcified enamel and [in ...
Children affected by allergies in the developed world: [2] 1 in 13 have eczema; 1 in 8 have allergic rhinitis; 3-6% are affected by food allergy; Children in the United States under 18 years of age: [3] Percent with any allergy: 27.2%; Percent with seasonal allergy: 18.9%; Percent with eczema: 10.8%; Percent with food allergy: 5.8%
A rigorous nine-year research review looking at the relationship between fluoride and intelligence in children concludes that as fluoride levels rise, IQ drops. Every 1 part per million increase ...

Allergic contact stomatitis is less common than allergic contact dermatitis because the mouth is coated in saliva, which washes away antigens and acts as a barrier. [7] The oral mucosa is also more vascular (has a better blood supply) than skin, meaning that any antigens are more quickly removed from the area by the circulation. [ 7 ]
This latest study is particularly noteworthy as it marks the 10th consecutive NIH-funded study in humans to identify harmful effects of fluoride on children’s developing brains. These findings add to the mounting evidence, underscoring the urgent need to stop adding fluoride to water systems and stop its promotion in public health policies.
For every small increase of fluoride found in kids' urine, Taylor wrote, “there is a decrease of 1.63 IQ points in children.” The researchers did not suggest that fluoride should be removed ...
