Now is it still necessary?An experiment in Windsor, Ontario (across the border from Detroit, MI):
> Yemmi Calito's children are patients of Dr. Meriano. The two oldest kids were raised on fluoridated water in Windsor and both have healthy teeth. Her two youngest weren't, and they've had to be treated for serious tooth decay. Calito said their oral hygiene habits are the same.
> "The younger two I feel they have more cavities," Calito said. "My little one, my three-year-old, actually had to go have general anesthesia … [about] four weeks ago to get his teeth fixed. They were in pretty bad shape."

Calgary, AB, stopped and has recently decided to restart:

The public voted in 2021 to stop:
> What’s happened since 2012? A study found that within a couple of years of ending fluoridation, decay in children’s baby teeth had risen by 65 per cent compared to 2005, while the increase was only 14 per cent in Edmonton, which continues to fluoridate its water. “We weren’t looking at little tiny cavities that needed to be fixed. They were large cavities, they were destroyed teeth,” says dental hygienist Denise Kokaram, who led a dental program for vulnerable Calgary youth in the wake of fluoridation’s discontinuation.
> In 2019, the University of Calgary’s public health institute summarized for council’s benefit the body of science on fluoridation—the abundant evidence that it curbs tooth decay in both children and adults, and the lack of conclusive evidence of the myriad harms that anti-fluoride activists allege, from bone deterioration to brain disease. (Authorities have lowered recommended fluoride levels in water to limit the risk of fluorosis, a condition that mainly causes mild tooth discoloration.)
