Why Does Your Breath Stink? You Might Be Surprised

If you just ate a plate full of garlic, or if you “forgot” to brush your teeth this morning, then your bad breath probably isn’t much of a mystery. Aside from strong foods, one of the most common reasons for bad breath is the bacteria that dwell in your mouth. Some oral germs result in tooth decay, and some facilitate gum disease, but others release volatile sulfur compounds that persistently foul your breath. If you practice good hygiene and still experience bad breath, then you might be surprised to find the reason behind it.

Other Reasons for Bad Breath


Prescription medications don’t directly cause your breath to stink, but dry mouth is a common side-effect of many medicines. Dry mouth describes a drastic decrease in saliva, which is your mouth’s way of naturally rinsing away food particles and bacteria. Your saliva also slows while you sleep, explaining why bad breath is so common when you first wake up in the morning.


Bronchitis, pneumonia, sinusitis, and other respiratory infections that involve nasal or sinus secretions can cause bad breath. A common cold could also be the reason if your nose is stuffy and dripping. If your bad breath persists after your respiratory illness clears, then visit Dr. Smith as soon as possible to determine the cause.


When you don’t consume an adequate amount of carbohydrates, your body turns to fat and protein as a source of energy. In this state, referred to as ketosis, your body will release chemicals into your bloodstream and breath that cause strong, persistent odors. The smell won’t go away with brushing, flossing, or strong mints and chewing gum, like other causes of bad breath might.
