The latest information published in 2022 shows 38.8 per cent of the country adds fluoride to municipal water, with little to no fluoride in New Brunswick, Quebec, Newfoundland and Labrador, Yukon, and British Columbia.
Any dentist in Toronto can tell you what Montreal teeth look like.
This whole thing started by a dentist who was investigating “brown stain” in a town in Colorado. Town water had very high levels of natural fluoride, causing mottling on teeth, but very hard enamel and almost no tooth decay. By the 1930s, the best levels were figured out. Now there is 100 years of data, but scientists now are considered wizards.
I was absolutely floored by this.

Some places (like in BC) have naturally occurring fluoride. It’s at like 1/4 the level but it’s still there.
