i remember when my 17 year old was an infant and his pediatrician found out that we had well water and he gave us a prescription for floride drops for the baby. i went so far as to fill the script. When I was almost ready to give the baby the floride i stopped and thought about what this might do to him. did i trust the government? did i trust that five years down the road they wouldn’t say “oops, its poison.” i threw it away and never used it. glad now that i thought for myself.
I had the prescription in hand 15 years ago and just didn’t fill it. None of my three kids have had a cavity. We are on well water.
