The cost effectiveness of fluoridating water supplies in new zealand

Communities adjust the amount of fluoride in their community water supply to optimal levels that protect teeth from decay - this is referred to as community water fluoridation.The rate of tooth decay (in permanent teeth) has declined in Canada from 74% of children in 1970-1972 to less than 25% in 2007-2009 as a result of a variety of factors, including widespread adoption of community water fluoridation (1).Effectiveness By preventing tooth decay, community water fluoridation has been shown to save money, both for families and for the health care system, and evidence continues to indicate that the economic benefit of community water fluoridation exceeds the costs (16; 20-22).Every
