I feel gross when I skip a shower for a day - I can’t comprehend how I’d feel after a month.
I feel gross if I don’t brush right after coffee. Can’t imagine a month.
Coffee is acidic. If you’re brushing right after coffee, you may be damaging the enamel of your teeth (acid + scrubbing is not a good combination). And it can’t grow back; once you’ve lost it, it’s gone forever.
Omg, I hate the internet.

Excuse me but I think the word you wanted to use there is figurative. Literal doesn’t mean literal anymore.

:P
