Here is a great article from cheatsheet.com regarding 6 Ways to Instantly Cure Bad Breath:
Americans today are obsessed with the concept of “being clean.” We are afraid of germs, odors, bad breath, you name it. Yet the world didn’t always operate this way. It wasn’t until the 1920s when Listerine was marketed as a cure for halitosis. Halitosis, or bad breath, actually wasn’t a problem until Listerine made it one. Thus begins our descent into a problem that now plagues over 65% of Americans.
Whether or not advertising created this falsehood about bad breath, (thanks Listerine!) bad breath is a condition that has plagued all of us at one point or another. If you have a low tolerance for horrible breath, it can actually ruin relationships and sour friendships. Sounds crazy, but bad breath is also a very embarrassing thing. No one wants to be known as the friend with constant bad breath.
Bad breath isn’t only caused by the foods you eat, but actually arises from various dental problems. Bad breath comes from oral ulcers, dental decay, oral infections, nose and throat infections, indigestion, food, medications, and even stress, anxiety, depression, alcoholism, fasting, and smoking.
Oftentimes, gum or mints don’t rid mouths of nasty odors, but luckily there are other ways to cure bad breath to ensure it won’t creep back 10 minutes later.
