2019年4月2日，美国食品药物监督管理局（ FDA ）提议修订瓶装水的质量标准，规定制造商在瓶装水中添加氟化物的含量不得超过0.7 mg/L。
部分原文报道如下：
This proposal is based on findings from evolving research on optimal concentrations of fluoride that balances fluoride's benefits in preventing tooth decay with its risk of causing dental fluorosis, a condition most often characterized by white patches on teeth. This proposed rule makes the standard for bottled water consistent with the U.S. Public Health Service's （PHS） updated recommendation for the optimal fluoride concentration for community water systems to prevent tooth decay. In addition, this rule may reduce consumer confusion regarding inconsistency in fluoride level recommendations. The proposed rule would not affect the allowable levels for fluoride in bottled water to which fluoride is not added by the manufacturer （but which may contain fluoride from its source water）。
