says it has .14% per pea sized glob.(Colgate) And if you swallow more than that you're supposed to call poison control?!?. Doesn't sound harmless to me. There's 1.0ppm in most fluoridated water. That's if you drank 4 glasses a day. They used 2.4 to 6.8 (see link, don't recall if mg or ppm) to slow down people with hyperthyroid. I was only addressing the thyroid issue. The rest of it is a bit scary to think about, frankly.

Sorry, here's the link listing "dosage".
