Evidence-based medicine requires evidence before medicating. Fluoridation of water is not evidence-based. It has not been tested in well-controlled studies. Fluoridation of public water is a default medication, since you have to deliberately avoid it if you do not want to take it.” ~ Andrew W. Saul
As a child, there was nothing I liked about going to the dental dispensary, with the possible exception of the large tropical fish aquarium in the waiting room. This was a distraction to what was coming: three hours in a vast hall containing a double line of black dental chairs and a matching double line of white-clad dental students. And that, as a six-year-old, is where I first met fluoride on a regular basis. After a free cleaning and checkup (the reason my cost-conscious parents had me go there, and the reason it literally took three hours to complete), fluoride was applied to my teeth with a swab.
I remember both the smell (acrid) and the taste (astringent). I actually looked forward to the fluoride treatment, simply because it was the last thing they did to me before I was allowed to leave. Did it work? Probably not. In addition to my regular topical fluoride treatments, I lived in a city with fluoridated water and was raised on fluoridated toothpaste. And I had a mouthful of amalgam by high-school graduation.
