Bad breath, also known as halitosis, can be an embarrassing and uncomfortable problem. It can be caused by a variety of factors, including poor dental hygiene, gum disease, certain foods, and medical conditions. While there are a number of ways to check if your breath smells, some methods are more reliable than others.
One of the simplest ways to check your breath is to lick the back of your hand and then smell it. If you can smell an unpleasant odor, it is likely that your breath also smells bad. Another way to check your breath is to ask a friend or family member to smell it. While this method may be more embarrassing, it can be more reliable than smelling your own breath.
