According to the Physician’s Desk Reference, the mucosal lining in the mouth has an absorption efficiency of over 90 percent! Because of this, fluoride has the potential to get into your blood and your cells IMMEDIATELY. Over 95% of toothpastes sold in the US now contain fluoride. Fluoride toothpastes sold in the US generally have between 1,100 and 1,450 parts per million of fluoride.This means that children who swallow too much fluoride toothpaste can suffer acute poisoning, even death. In fact, a single tube of bubble-gum flavored Colgate-for-Kids toothpaste contains enough fluoride to kill a child weighing less than 60 pounds!
