What we’re seeing in Calgary is an increase in dental decay over the past few years since they removed fluoride from the water so it’s important to have that in our water to help strengthen our teeth.”Before the city halted the practice, fluoridation of drinking water cost an estimated $750,000 every year. The cost is well worth the health of the children.
