Community water fluoridation and individual use of fluorides have brought about a marked reduction in the prevalence of dental caries in the United States during the past 35 years. There is evidence that the prevalence of caries is declining in communities with unfluoridated water as well as in those with fluoridated water. This phenomenon may be related to an increase of fluoride in the food chain, especially from the use of fluoridated water in food processing, increased use of infant formulas with measurable fluoride content, and even unintentional ingestion of fluoride dentifrices. This trend should encourage reevaluation of research priorities and previously accepted standards for optimal fluoride use.
在过去35年里，社区水氟化和个人使用氟化物已使美国龋齿患病率显著降低。有证据表明，在未进行水氟化的社区以及进行了水氟化的社区中，龋齿患病率都在下降。这种现象可能与食物链中氟化物增加有关，特别是食品加工过程中使用了含氟水、含可测量氟化物的婴儿配方奶粉使用增加，甚至是无意中摄入了含氟牙膏。这一趋势应促使人们重新评估研究重点以及先前公认的最佳氟化物使用标准。
