High Fluoride Exposure Increases Tooth Decay
Studies: HIgh fluoride levels in water increase tooth decay risk “Logistic regression analyses indicated that subjects in the high-F and urban Arusha municipality were at a significantly higher risk of dental caries than children in the low-F areas.” SOURCE: Awadia AK, et al. (2002). Caries experience and caries predictors – a study of […]

Infants Have Impaired Ability to Excrete Fluoride
“Approximately 80% of an absorbed dose of fluoride is retained in young children compared to 50% in adults. This is supported by the finding that renal fluoride excretion rate is lower in children than adults. This difference in fluoride retention is due to high fluoride uptake in developing bones.” SOURCE: Agency for Toxic Substances & […]

Fluoride: Developmental Neurotoxicity.
Developmental Neurotoxicity There has been a tremendous amount of research done on the association of exposure to fluoride with developmental neurotoxicity. There are over 60 studies reporting reduced IQ in children and several on the impaired learning/memory in animals. And there are studies which link fluoride to Attention Deficit Hyperactivity Disorder. Teaching Tool Available Chris […]

Fluoride’s Effect on Fetal Brain
The human placenta does not prevent the passage of fluoride from a pregnant mother’s bloodstream to the fetus. As a result, a fetus can be harmed by fluoride ingested pregnancy. Based on research from China, the fetal brain is one of the organs susceptible to fluoride poisoning. As highlighted by the excerpts below, three Chinese studies […]

Warnings from Dental Researchers: Infants Should Not Receive Fluoridated Water
A baby drinking formula made with fluoridated water receives a very high dose of fluoride. This is because fluoridated water contains 200 to 250 times more fluoride than breast milk and, unlike other age groups, a newborn infant’s entire caloric intake comes from liquid. The provision of fluoridated water to infants presents an historically unnatural […]

Fluoride & IQ: 76 Studies
Note: See the Updated list of fluoride IQ studies at https://fluoridealert.org/researchers/fluoride-iq-studies/the-fluoride-iq-studies/ • As of July 18, 2022, a total of 85 human studies have investigated the relationship between fluoride and human intelligence. • Of these investigations, 76 studies have reported that elevated fluoride exposure is associated with reduced IQ in humans. • The studies which […]

The Problems with Infant Exposure to Fluoridated Water
Breast milk protects Infants from fluoride: “[P]lasma fluoride is poorly transferred to breast milk and infants thus receive almost no fluoride during breast feeding… The existence of a physiological plasma-milk barrier against fluoride suggests that the newborn is actively protected from this halogen. Hence the recommendation made in several countries to give breast-fed infants fluoride […]

NIDR’s National Survey of Oral Health in the U.S. (1986-87)
In the 1986-87, the National Institute of Dental Research (NIDR) conducted the largest ever study of childhood dental health in the United States. The study examined the teeth of 39,207 schoolchildren from 84 communities across the country, including communities that fluoridate water and communities that do not. The results of the study were published in two papers–one authored […]

Studies on Tooth Decay Rates After Water Fluoridation Is Stopped
For decades, the American Dental Association (ADA) has long warned that if communities end their water fluoridation programs, the rate of tooth decay will increase. In it’s “Fluoridation Facts” brochure, the ADA states: “Dental decay can be expected to increase if water fluoridation in a community is discontinued for one year or more, even if […]

Fluoride & Tooth Decay: Topical vs. Systemic Effect
When water fluoridation first began in the 1940s, dentists believed that fluoride’s main benefit to teeth came from being swallowed during the tooth-forming years. Today, the overwhelming consensus by dental researchers is that fluoride’s primary effect is topical, not systemic, and that this topical effect occurs after the teeth have erupted into the mouth (i.e., post-eruptive), not before. There is no need, therefore, to swallow fluoride, especially during infancy and early childhood.
