Test Your Breath Trust in your personal sense of smell. A quick, private reliable way to check your breath is to use a cotton swab or gauze to wipe the top back surface of the tongue. If you smell a bad breath odor emanating from the swab, you can be reasonably sure you have bad breath. Neurologically, the sense of smell and the sense of taste report to two distinct centers in the brain, however there is physical evidence which show that the receptors for these are separate senses often intermingle with each other. This causes some to detect a sense of odor, even though there is none, based on stimulation in the taste center, and vice versa. Pharmaceutical companies realized early on that it could be very easy to 'fool' the public by creating strong flavors in oral rinses, which would then be 'sensed' by the brain as if the user's breath was fresh. You can have a great minty taste in your mouth and simultaneously be releasing offensive bad breath odor as you exhale! Some popular mouthwashes have a strong 'mediciny' taste, designed to create in the mind of the user a sense that the mouthwash is effective, when it may be actually making the bad breath situation worse. The mouthwash user tastes the flavor, but the is not aware that offensive bad breath odors still persist.
