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.
