For some time now, the Internet has been spreading the claim that toothpastes containing fluoride are harmful. Opponents of fluoride warn that fluorides are especially toxic for children. Fluoride is a rat poison and pesticide. That is why toothpastes that do not contain fluoride are advertised strongly again and again.
Misunderstanding fuels fear
In fact, the fear of fluoride-containing toothpaste is based on a misunderstanding, as toxicologists say: many people confuse fluoride with fluorine. Fluorine is a very aggressive, poisonous gas, which is only liquid at minus 180 degrees, it eats through all materials. But fluorine gas is different from fluoride. Fluoride is the negatively charged ion, which together with sodium produces a relatively harmless salt. According to dentists, fluoride is safe in the form and dosage used to fight caries. A person weighing 60 kilograms would have to eat 20 tubes of toothpaste a day to reach an alarming threshold. If you use toothpaste properly and brush your teeth two or three times a day, there will be no negative effects.
