If you have have bad breath, it's most likely caused by a build of bacteria, particularly on the tongue. You're better off using a tongue scraper than temporarily disguising it with mouthwash.

...And flossing.

I just brush my tongue. I remember telling a friend once that your tongue should be pink. They had no idea and just thought having a grey tongue was totally normal...

Yep. You know all those gross pics of that disgusting slob Miley Cyrus sticking her tongue out like a slobbering idiot? Every time I accidentally notice one on the internet, I just KNOW she has to have really terrible breath from how discolored her tongue is. Euch!

2 things:
1) "floor cleaner" Listerine is most likely a different thing than mouth wash Listerine.
2) Just because they invented the term, doesn't mean it's not a legitimate medical condition. They just marketed it...

As far as I know, they didn't touch the recipe when they transitioned, but why would they if the original recipe was just fine for anything. Very hard to find any actual knowledge how it's changed over the years, I guess the old bottles have no information what they actually contain?
