Use Around The World
Much of the early work on establishing the connection between fluoride and dental health was performed by scientists in the USA during the early 20th century, and the USA was the first country to implement public water fluoridation on a wide scale. It has been introduced to varying degrees in many countries and territories outside the U.S., including Argentina, Australia, Brazil, Canada, Chile, Colombia, Hong Kong, Ireland, Israel, Korea, Malaysia, New Zealand, the Philippines, Singapore, Spain, the UK, and Vietnam. An estimated 12 million people in western Europe, 204 million in the U.S. (66% of the U.S. population), and 355 million worldwide receive artificially fluoridated water, in addition to at least 50 million worldwide who receive water naturally fluoridated to recommended levels.
In addition, at least 50 million people worldwide drink water that is naturally fluoridated to optimal levels; the actual number is unknown and is likely to be much higher. Naturally fluoridated water is used in many countries, including Argentina, France, Gabon, Libya, Mexico, Senegal, Sri Lanka, Tanzania, the U.S., and Zimbabwe. In some locations, notably parts of Africa, China, and India, natural fluoridation exceeds recommended levels; in China an estimated 200 million people receive water fluoridated at or above recommended levels.
Communities have discontinued water fluoridation in some countries, including Finland, Germany, Japan, the Netherlands, Sweden, and Switzerland. This change was often motivated by political opposition to water fluoridation, but sometimes the need for water fluoridation was met by alternative strategies. The use of fluoride in its various forms is the foundation of tooth decay prevention throughout Europe; for example, France, Germany, and many other European countries use fluoridated salt.

Famous quotes containing the words the world and/or world:
“This might be the end of the world. If Joe lost we were back in slavery and beyond help. It would all be true, the accusations that we were lower types of human beings. Only a little higher than apes. True that we were stupid and ugly and lazy and dirty and, unlucky and worst of all, that God Himself hated us and ordained us to be hewers of wood and drawers of water, forever and ever, world without end.”
—Maya Angelou (b. 1928)
“I consider women a great deal superior to men. Men are physically strong, but women are morally better.... It is woman who keeps the world in balance.”
—Mrs. Chalkstone, U.S. suffragist. As quoted in History of Woman Suffrage, vol. 2, ch. 16, by Elizabeth Cady Stanton, Susan B. Anthony, and Matilda Joslyn Gage (1882)
