Fluoride Supplements: Healthy or Harmful?

Although many dentists prescribe fluoride supplements, also known as tablets, drops, lozenges, rinses, and vitamins, these products are potentially harmful.

The IAOMT is concerned that the amount of fluoride taken in throughout a lifetime from all sources, including the water supply, exceeds the human tolerance for this toxic substance, and as a result, can potentially harm both children and adults. Furthermore, the IAOMT is particularly alarmed that infants can be overdosed when fed with fluoridated tap-water-formula.

While some evidence suggests that topical applications of fluoride (such as brushing with a fluoride-containing toothpaste) might lower the incidence of tooth decay, evidence also suggests that swallowed toothpaste can contribute to childhood overdose. Additionally, the IAOMT has recognized that there is strong evidence to support potential harm from systemic exposure to fluoride. In fact, based on an ongoing examination of the toxicological data on fluoride, the IAOMT has made several preliminary determinations over the last 18 years: Each time, the IAOMT has concluded that fluoride added to the public water supply and fluoride prescribed as controlled-dose supplements deliver no discernible health benefit, but on the contrary, these uses of fluoride can actually cause a higher incidence of adverse health effects.
