On: Bioethicist proposes adding lithium to US drinking...

[caf]

Dental caries can kill - that's how the guy that played Lorne on Angel died - so we're talking about more than "cutting down on a few bucks of dental care expenses".

Dental caries can be prevented by flossing your teeth, then spitting (most of) the fluoride out.

Or even better, by avoiding sugar and eating calcium rich vegetables.

[caf → euccastro]

Certainly, but that doesn't change the point that saying it's about "cutting down on a few bucks" is overly downplaying the potential benefit.

TFA doesn't even mention death by caries, only the savings. If avoiding those deaths was the reason, I guess lithium would have been used before fluoride. I don't know the stats, but I know of several people that committed suicide in my area and never heard of a single death by caries.
