Total fluoride intake should be determined before prescribing more, reported former New York State Department of Health Dental Director, J. Kumar, He wrote: “Because of the availability of fluoride from multiple sources, practitioners should prescribe other forms of fluoride therapy based on an understanding of patients’ total exposure to fluoride and the need for it,” (
NYS Dental Journal February 1998). Few dentists, if any including him, heed that advice.
The American Dental Association concurs: "It also
is critical that the dentist assess a child’s total fluoride
exposure from all sources (beverages, food, toothpaste,
supplements, topical applications and so forth..." (
Journal of the American Dental Association 2014)
Never is fluoride intake tallied when communities are pressured to continue or start fluoridation. Legislators should know much fluoride children already ingest before feeding them more via their water supply.
The daily upper limits (UL) for fluoride are listed below, according to the National Institutes of Health Office of Dietary Supplements (Taking more than the UL can be harmful and not recommended)
Life Stage | Upper Limit |
---|
Birth to 6 months | 0.7 mg |
Infants 7–12 months | 0.9 mg |
Children 1–3 years | 1.3 mg |
Fluoride sources are many:
Absent from labels, fluoride is in virtually all f
oods and beverages, including, soda,
baby foods and
all infant formulas, It’s high in
tea (up to
6 mg/L, according to the US National Institutes of Health),
ocean fish and
soy products.
And,
because of fluoride-containing
pesticide residues, all grapes and its products (raisins,
juice, wine, jellies, jams) have a significant fluoride content.
Foods
made with mechanically separated (boned) chicken, such as canned meats, hot
dogs, and infant foods, also add fluoride to the diet (J Agric Food Chem Sept 2001) "A single serving of chicken sticks alone would provide about half of a child's upper limit of safety for fluoride," the researchers report.
Fluoride ingested daily from toothpaste ranges from 1/4 to 1/3 milligram (
National Institutes of Health) “Gels used by dentists are typically applied one to four times a year and can lead to ingestions of 1.3 to 31.2 mg fluoride each time.”
Other sources come from feed regimens of animal products, animal products; food storage containers (Teflon-coated containers); and food packaging (migration of perfluorochemicals into food).
"eggshells also contain trace amounts of minerals that promote bone health, such as strontium, fluoride, magnesium, and selenium...their powdered form is used in dietary supplements"
How much is too much?
According to the National Academy of Sciences, “without causing unwanted side effects including moderate dental fluorosis,” (yellow splotched teeth), the adequate daily intake of fluoride, from all sources, should not exceed: (But does)
-- 0.01 mg/day for 0 – 6-month-olds (which is in every infant formula – concentrated or not)
-- 0.5 mg/day for 7 through 12 months
-- 0.7 mg/day for 1 – 3-year-olds
-- 1.1 mg/day for 4 – 8 year olds
The EPA regulates water fluoride levels to
protect against fluoride-caused bone damage. So It's important to know that fluoride concentration in drinking water does not equate to an individual's daily dose. Fluoridation should never begin without fore knowledge of the community's fluoride intake from all sources.
According to "Fluoride contamination, consequences and removal techniques in water: a review," in the journal Environmental Science: Advances (Issue 5, 2022),
"The sources of fluoride in the environment include industrial plants, aluminum smelters producing glass brick, hydrofluoric acid, tile works and phosphate fertilizer plastic factories, textile dyeing, and industries that consume high sulfur non-coking coal for thermal power. Currently, high-tech companies developing semiconductors and integrated circuits produce significant fluoride-containing industrial wastewater. Cigarettes, which contain an average of 236 ppm fluoride, play a significant role in human fluoride consumption. Teflon-coated cookware may potentially increase the fluoride absorption in humans. The fluoride concentrations in Teflon-coated cookware is as high as almost 3 ppm, whereas it is lower in aluminum cookware. Also, the fluoride concentrations are high in stainless steel and Pyrex ware, although to a lower extent. In normal and high quantities, fluoride in water may cause aluminum to leach from cooking utensils and copper from pipework.
