To the Editor This letter is in response to the Editorial, “Is Fluoride Potentially Neurotoxic?”,¹ published online on August 19, 2019. While stating the position of the US Centers for Disease Control and Prevention in support of water fluoridation (WF), the Editorial mentions some of the opposition arguments that merit addressing.

Water fluoridation is the adjustment of natural fluoride levels in water to safely maximize caries prevention on a population level. Water fluoridation is not considered as medication to treat existing disease but provides disease prevention. Water is safe to drink if it meets regulatory standards, and WF at 0.7 mg/L (ppm) is well within those standards. The courts have ruled that WF is not compulsory because consumers have choices with bottled water and filtration systems.² Each community provides consent through its voters or elected representatives. Water fluoridation is not administered indiscriminately but is well controlled within a narrow range around the target 0.7 ppm level.³

给编辑的这封信是响应社论“为氟化物潜在的神经毒性？”，¹ 8月19日在网上公布，2019年虽然陈述美国疾病控制和预防的位置，支持水中加氟（WF） ，《社论》提到了一些值得解决的反对派论点。

水氟化是对水中天然氟化物含量的调节，以在人群中安全地最大限度地预防龋齿。水氟化不被认为是治疗现有疾病的药物，但可以预防疾病。如果水符合法规标准，则可以安全饮用，而WF的浓度为0.7 mg / L（ppm）也在这些标准之内。法院裁定WF不是强制性的，因为消费者可以选择瓶装水和过滤系统。²每个社区都通过其选民或民选代表表示同意。水氟化不是随意进行的，而是可以很好地控制在目标0.7 ppm范围内的狭窄范围内。³
