For the past two years, when I take the rugrats to the peditrician, the doctor always ask if we have floridated drinking water. (We do). It would be nice if they were collecting this data to see how many children who drink floridated water get cancer, but I suspect it is more along the lines of, "do you have a gun in your home".
As a small child, we didn't have fluoride in our water or our toothpaste. I must tell you, all the kids I knew had terrible teeth. We would go to the dentist and have five or six cavaties every time. After the fluoride treatments, our teeth were much better. Of course, you could use fluoride toothpaste as well. I am older now and my teeth are still good. One woman would not let her kids have fluroide at all-bottled water etc. The kids teeth are terrible, they will need a complete bridge by 21.
