Bad breath is something everyone can relate to. Whether it’s a result of just having woken up in the morning or eaten food with garlic in it, it occurs very frequently.
Halitosis—the medical term used to describe chronic bad breath—is also quite common, affecting 25% of people worldwide, according to Medical News Today. Unfortunately, however, a quick brush of the teeth may not easily rid of it, as some of its causes extend beyond simply having consumed something pungent.
While bad breath often starts in the mouth, there are many possible causes. Let’s take at six of the most common contributing factors for halitosis.
As with casual bad breath, halitosis can also be caused by the foods a person consumes. According to the Mayo Clinic, this is because “the breakdown of food particles in and around your teeth can increase bacteria and cause a foul odor.” These foul odors are particularly pronounced after having eaten foods such as onions, garlic and certain spices because “after you digest these foods, they enter your bloodstream, are carried to your lungs and affect your breath.”
The National Health Service also adds that drinking beverages like coffee and alcohol, which have strong odors, can be other contributing factors to chronic bad breath.
