There are lots of reports on the toxicity of flouride on this website and others. Sodium Laurel Sulfate is bad too. I have a document from the American Academy of Neural Therapy/Neural Kinesiology. They work extensively with understanding toxic substances and have a lengthy document summarizing their product recommendations. The recommendations are based on the ingredients and testing of the product. Some products can have OK ingredients, but solvents were used to extract them and therefore make them toxic again. They list Real Purity (1-800-253-1694, Oxyrich, Xylifresh, Auromere, Edodent Tooth Powder, and Peelu as good toothpastes. The ones that you might think are good but are really bad are Tom's, Weleda, Homeodent and Nature's Gate.
