Extra Gum: Tongue Test
It's hard to tell if you've got bad breath, unless people crumple like a paper cup when you open your mouth.
You'd think with all our technology, there would be a better way by now to test your breath than the ol' palm 'n' sniff.

Well, bad breath is acidic. So, if you lick a bit of litmus paper, and it registers as acidic, the chances are you could do with a Wrigley's.
