Nope, it's all good.

I heard it was bad for your teeth

Carbonated water is actually good for you - raising your levels of CO2 is beneficial. There is some discussion that it can raise stomach acid secretions however i'd say most people dont produce nearly enough stomach acid so... it would be fine. With that said - I am referring to mineral carbonated water (gerolsteiner (which i happen to be drinking right now), apollinaris, etc)

Great, i might add it to my diet.

Any other thoughts ?

Carbonation makes my acne break out. Within 48 hours of having carbonated water, I'll have a break out. My research online shows that carbonated water is good for me but that doesn't seem to be the case for my skin. Does anyone else have this issue?

No carbonated water is not bad. Some sweetened soda can increase calcium loss or cause acne.
