Whether you're headed to a job interview or going out on a date, it's important for your breath to smell fresh and clean. Bad breath, also called halitosis, can have a damaging effect on personal and professional relationships. Breath odor often crops up even if you brush your teeth and practice good dental hygiene. You're used to the way your own mouth smells, so it isn't always easy to tell if your breath has a bad odor. You can check for offensive smells with a few quick tests.
Wash your wrist to remove perfume, cologne or any other scented products. Lick your wrist and wait for about 10 seconds. Smell the licked area. If your wrist smells bad, your breath has a similar odor.
Floss your teeth and then check the floss for blood. Bleeding gums may indicate gum disease, which causes mouth odor. The floss also may smell bad.
Rub the back of your tongue with a cotton swab or toothpick. Wait for about a minute and then smell the object. Your breath generally has the same odor as the object.
Ask a friend or other trusted person if your breath smells. You may find this embarrassing, but it's one of the most reliable tests you can do.
Cup your hand and breathe into it. This is the least reliable way to check for breath odor.
