It's easy to wonder how to help bad breath go away because the cause isn't always something you ate – dry mouth often plays a part at some point. Oral deficiencies like dry mouth are normal symptoms of everyday stress, according to the National Institutes of Health (NIH), and many usual life events are stressful enough to cause it: a job interview, first date or something that can make an unpleasant smell just as embarrassing.
Rest assured there are simple and discreet ways to combat dry mouth. Consider these methods the next time you want to make a great first impression.
Stress and Dry Mouth
Decreased saliva flow is the primary reason for dry mouth, which can lead to bad breath. In other words, stress results in dry mouth because it contributes to this decrease in saliva flow.
How? Dehydration and breathing through the mouth contribute to dry mouth, and in stressful situations, you may be too busy to eat, drink or breathe normally. That's why dry mouth may be more likely when, for example, you are at a job interview or on a first date.
