Water fluoridation - Wikipedia

Supply of fluoridated water forces those who do not so wish to also consume water with added fluoride. This approach is therefore not accepted in most countries in the world." [83] [84] This change was often motivated by political opposition to water fluoridation, but sometimes the need for water fluoridation was met by alternative strategies.
