How things change. My 4 boys (ages 14 to 20) were born in Montreal where the city water wasn't fluoridated. I was very encouraged by my family doctor to give my oldest some kind of vitamin drops (triviflor?) to make sure he didn't get cavities. He was the only one who wasn't breasted for an extended amount of time and the only one who got those vitamins. Guess which kid had a ton of cavities in his baby teeth?
