Sounds like Seltzer water is very healthy to drink.  But maybe your reference to soda pop was a more humorous way to say “sugar”?  Sugar is the main ingredient in soda pop, yes.

Is it healthier than regular soda, or just better for your teeth?
assistant
Is carbonated water, very healthy to drink? I mean just water with CO2 infused?
user
It is healthy if you use it to hydrate, or drink it as a tonic.  Carbonated water with pure CO2 is very healthy and healthy to drink regularly.  But yes, I believe there are much better ways to hydrate, so I’d strongly recommend just drinking regular water.

I tend to drink seltzer water daily. I prefer to get seltzer water without sodium, because it's just healthier.
user
I’ve heard that Seltzer water is often used as a carrier for various "cocktails" that some people are making, but I'm not sure what those are.
assistant
It's a great option to normal soda pop, sugar wise.
