My daughter came back from the dentist the other day and reported that Vancouver does not fluoridate its water system.

미국에서 자란, where water fluoridation is quite routine, I was surprised to learn of this fluoride policy.

I discovered that, according to Health Canada, 이하 캐나다인의 절반 이상 (거칠게 45 퍼센트) receive fluoridated water.

이기는하지만 Health Canada supports water fluoridation as a way to reduce tooth decay, the decision to fluoridate water is a local one in Canada.

토론토, 해밀턴, 런던, and Edmonton are among the cities with fluoridated water. Water is not fluoridated in Vancouver, 빅토리아, 몬트리올, 나 퀘벡시에게. Calgary previously fluoridated the city water, 하지만 its city council voted in 2011 to discontinue the practice.

미국에서는, 이상 70 percent of Americans — or more than 204 만 명 — on community water systems have fluoridated water.

The percentage is even higher in Australia, 어디에 대략 90 percent of the population receives fluoridated water.

영국의, like many European countries, has taken the opposite approach. 이하 10 percent of U.K. residents have fluoride added to their water supply.

One of the many unexpected things you learn when you move to a new country!
