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

संयुक्त राज्य अमेरिका में बड़े हो गए, where water fluoridation is quite routine, I was surprised to learn of this fluoride policy.

I discovered that, according to Health Canada, कनाडाई की तुलना में आधे से कम (लगभग 45 प्रतिशत) receive fluoridated water.

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

टोरंटो, हैमिल्टन, लंदन, and Edmonton are among the cities with fluoridated water. Water is not fluoridated in Vancouver, विक्टोरिया, मॉन्ट्रियल, क्यूबेक सिटी या. Calgary previously fluoridated the city water, लेकिन its city council voted in 2011 to discontinue the practice.

में अमेरिका, से अधिक 70 percent of Americans — or more than 204 लाख लोगों को — on community water systems have fluoridated water.

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

यू.के., like many European countries, has taken the opposite approach. कम से कम 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!
