We have well water and my pediatrician asked if we wanted to get flouride drops 4 years ago. I said no. Now the dentist is after us. I have been telling them no too. Thank goodness I researched this earlier, but it is always nice to get confirmation of the decision, this is overwhelming though.
By the way, my sisters and I were raised with well water and I think that my sisters each have one cavity. I have none.
