Hey, mb, congrats on posting the most important message I've ever seen on this board! Regardless of which side of the "lesser of two evils" everybody's politics may fall on, this is a crucial election; get out and vote, PLEASE!
We don't have floride in our water so I must spend bucks on treatments for the kids, Vitamins and rinses. My 8 year old has had a root canal already. If it is in your water you do not need to take fortified vitamins or do the rinses. Just be careful with how much is ingested. Have the water tested often to keep levels in check.
