Is fluoride poisonous?
The facts: Toxicity is related to the dose of a substance rather than merely exposure to the substance itself. Many substances (eg chlorine, iodine, fluoride, iron, salt, vitamins A & D, antibiotics, painkillers, oxygen, and even water) can be dangerous at very high levels, but beneficial and even essential at low levels. Fluoride is a naturally occurring substance, and even after increasing the amounts of fluoride to optimal levels, the level in drinking water is less than one part per million. In 1993, the US Agency for Toxic Substances and Disease Registry stated: “When used appropriately, fluoride is both safe and effective in preventing and controlling cavities.
