Coke is 89% water (from the other % most is sugar).

Not really comparable to consuming 2 cans of salt, baking soda, toothpaste, etc.

And would you really be worried for people drinking several cans of lemon juice per day?

Straight lemon juice in those quantities is actually bad for the teeth. As in, my sister used to eat lemons like oranges and quit because of that.

The most apt comparison with lemon juice to coke would be lemonade, though. And some folks do drink quite a bit of that.

Yes, absolutely. It's pretty damaging to teeth if consumed regularly, AIUI.

(Personal experience: I once started drinking a few glasses of orange juice (weaker than lemon) daily, within a year I needed four fillings. Stopped drinking it immediately afterwards, haven't needed fillings before or since).

That likely had more to do with the sugar than the acid in the juice.

I'd been drinking apple juice in similar quantities before and since for years (when I say "started" I really mean I switched from apple to orange), which I believe has similar sugar content.

Don't know about your teeth, but that sugar is pushing for diabetes. Drinking juice straight (not diluted with water) at 100+ kCal/cup rate, in quantity, is a bad idea

Yeah, this is a few years back now; I spoke to a nutritionist last year for the first time in my life and that was the first thing she told me to cut (and I have).
