pH values in food vs stomach acid

Here is a table that I found of common pH values... and it doesn't look like stomach acid is THAT much more highly acidic than, say, vinegar or lemon juice, which at least I commonly use in cooking and in teaspoon amounts to stop myself from eating other things.

If the huge concern about purging is that stomach acid rots your teeth, shouldn't people also be getting warnings about consuming too much vinegar or lemon/lime juice? I know that when I purge, I also a) drink a ton of water beforehand to hopefully dilute some of the acid and b) rinse my mouth out afterwards. I never do that when eating pickles or making stir-fry (I use lemon or lime juice to stirfry veggies in, in lieu of oil). So which is hurting my teeth more? The throwing up, or the 'sensible' eating habits/crutches I try to use to prevent myself from doing that?

Thoughts?
