Fluoride Exposure During Infancy:
In contrast to recommendations adopted in the 1950s, fluoride supplementation is no longer recommended for newborn children. This includes both fluoride in drops, and fluoride in drinking water.Not only is fluoride ingestion during infancy unnecessary, it can also be harmful - as suggested by a mounting body of evidence linking fluoride exposure during the first year of life with the development of dental fluorosis. (For pictures of dental fluorosis,click here)Because of the risk for dental fluorosis, and the lack of demonstrable benefit from ingesting fluoride before teeth erupt, the American Dental Association - and a growing number of dental researchers - recommend that children under 12 months of age should not consume fluoridated water while babies under 6 months of age should not receive any fluoride drops or pills.Fluoridated drinking water contains up to 200 times more fluoride than breast milk (1000 ppb in fluoridated tap water vs 5-10 ppb in breast milk). As a result, babies consuming formula made with fluoridated tap water are exposed to much higher levels of fluoride than a breast-fed infant. (A baby drinking fluoridated formulareceives the highest dosage of fluoride among all age groups in the population(0.1-0.2+ mg/kg/day), whereas a breast-fed infant receives the lowest).Dental fluorosis is not the only risk from early-life exposure to fluoride. A recent review in The Lancet describes fluoride as "an emerging neurotoxic substance" that may damage the developing brain. The National Research Council has identified fluoride as an "endocrine disrupter" that may impair thyroid function, while recent research from Harvard University has found a possible connection between fluoride and bone cancer.
