10 surprising causes of bad breath you didn’t know

6. Breathing Through Your Mouth

Some people breathe through their mouths only when they are too stuffed up to breathe through their noses. Others however, have fallen into the habit of breathing through their mouths all the time. When you have bad breath to begin with, mouth breathing does not help your case! Those who didn’t start out with bad breath will soon find that by breathing through their mouths, they have given themselves bad breath. When your mouth is open for long periods of time, it dries out and a dry mouth is one of the causes of bad breath. Practice breathing through your nose as often as you can, and soon you’ll become more aware of your mouth breathing. After a while, you’ll be breathing through your nose all the time.
