O.k., so here is what we know. Germany administered fluoride through drinking water to its citizens and prisoners. According to you, I guess, Hitler just cared about their teeth. Never mind the 100's of scientific studies that prove the neurological damage fluoride causes. Here's a few:
Influence of Fluoride Exposure on Reaction Time and Visuospatial Organization in Children,

Perhaps you know of some journals that report ingestion of fluoride as beneficial. I wont hold my breath.
