The Federal government says the amount of fluoride in America’s drinking water should be reduced. This is the first change in fluoride recommendations in more than half a century.
Seventy years ago, Grand Rapids, Michigan was the first city in America to fluoridate its water; a decade later Canton was the first in Ohio. And, in 1962, the U.S. government said to improve dental health, all public water should include a fluoride additive of about 1 part per million.
Not much changed until this week.
