Ray,
I have never heard that before, that CO2 is bad for enamel on teeth. Perhaps Brian can enlighten us. In a Google search all I could find was mostly anecdotal evidence that "carbonic acid" is formed by the CO2, similar to acid rain, but in minute amounts.

In my case it's not the enamel that's causing the problems, it's the root exposure from gum recession caused by the radiation.

I only drink bottled water now when required by convenience, prefering tap water when at home or in restaurants.
