Thanks for the link. Interesting about the link between flouride and lack of iodine.
About 2 months ago I replaced the household's toothpastes with Tom's of Maine (flouride-free). We all just had check-ups and have no dental problems.
It's horrifying to me now that I was convinced by my daughters' pediatric dentists to supplement them with flouride tablets. I didn't do it for long; somehow it felt counter-intuitive. Now I have solid reasons for keeping flouride out of this household.
