Before I knew fluoride was bad for people, I made the mistake of using Nursery Water to mix up my daughter's baby formula. When her permanent teeth started coming in I noticed that they had lighter white patches on them. The dentist said it was from fluoride. Now my daughter's teeth are permanently damaged and who knows what effect it had on her brain and the rest of her body. I have to live with this guilt for the rest of my life and also the uncertainty of what the future may hold for my 8 year old daughter.
