It never made any sense to add fluoride to the water supply for the ostensible reason of tooth decay prevention. If you want to use fluoride as an oral hygiene aid, you can always rinse your mouth with it, but that's no reason to ingest flouride into your body ! This chemical is known to dumb people down. It has known adverse effects on the central nervous system with prolonged use.

I suspect that the REAL reasons for adding fluoride to the water supply are totally different from the stated reasons.
