下麵是ADA的公告:

看上文的最後一段:
...insure children do not ingest too much fluoride. The good news is that parents and other caregivers can monitor the use of all fluoride-containing products by children younger than 6 years by placing only a pea-sized amount of fluoride toothpaste on a young child’s toothbrush at each brushing. Young children should be supervised while brushing or using a mouthrinse so they learn to spit, and not to swallow. Before the age of two, children should not be allowed to use a fluoride toothpaste for brushing. 這裏有更加有意思的公告: http://ebd.ada.org/contentdocs/ADA_Evidence-based_Infant_Formula_Chairside_Guide.pdf 簡單點說吧:美國的自來水裏氟化物的含量不是太低了,而是太高了,特別是對幼兒。
