If I ain't wrong, fluor is an oxidant and as such is dangerous for health. Wikipedia says that Fluoride is toxic and causes death in high dosage. In low dose, it can still cause fluorosis, with effects yellowing of teeth, hypothyroidism, or brittling of bones and teeth.

In any case, you'd be better off drinking bottled mineral water than tap water (I don't trust governments and public pipelines). Another serious health concern with tap water is lead, if your house or your building still has lead pipes (should be prohibited, it is as much of a hazard as asbestos !). This not only causes brain damages, it is responsible for antisocial behaviours and personality disorders.
