To my mind, yes sure you can over complicate the entire debate, but all of that is irrelevant in the face of these basic points:
- Is there a chance that fluoride ingestion could be detrimental to human health? - Can tooth decay be prevented by diet and brush/floss with good quality toothpaste?
Presumed safety of chemicals (at the behest of organizations) to human/environment until proven otherwise is shocking to me.
They irony of all this is that if you want to buy good quality toothpaste you are forced to import it from overseas, due to the FDA limiting ingredients in toothpaste.
