I thought that although I could not find who has the most fluoride in their tooth paste you may like to know the flip side of fluoride before taking to much. This is just one view point I copy a little for your review but please refer to the site in the source to read all.
Fluoride is one of the most toxic substances known to man, yet based on its inclusion in virtually every brand of toothpaste, the American Dental Association believes it’s okay to use fluoride for preventative dental care. Other products, such as bottled water, infant formulas, and even vitamin supplements, now contain fluoride!
Every year Poison Control centers receive thousands of calls from people reporting excessive consumption of fluoride-containing products, such as vitamins, toothpaste, mouthwash, etc. Fluoride poisoning severely damages the body and can be fatal. This lethal chemical creates a toxic state that can cause a variety of harmful effects.
Just something to think about =)
