What Causes Bad Breath?

Many causes can contribute to bad breath, such as:


Some food items like garlic, onions, or cabbage can cause bad breath. After digestion, these foods circulate in your blood and exit through your breath, giving it a foul odor. Also, the buildup of tiny food particles in your mouth provides bacteria nourishment, allowing them to grow. These bacteria cause bad breath.


Cigarette smoking leaves your mouth dry, which causes bad breath. Moreover, the smell of cigarettes makes your breath bad.

Smoking is also a cause of gum disease, which can compromise the health of your oral cavity, leading to bad breath.

Dry Mouth

Your saliva is your friend in preventing bad breath. It washes away and kills the bacteria, keeping your mouth clean. When your mouth goes dry, it can lead to bad breath. It is a dry mouth that makes your breath foul-smelling when you wake up in the morning.

Xerostomia is the term doctors use for dry mouth. It can occur if there is some problem with your salivary glands or in some health conditions like Sj√∂gren’s syndrome.

Poor oral hygiene

You may be feeling lazy and think of skipping brushing your teeth before going to bed. But lack of proper brushing gives bacteria in your mouth the opportunity to feed on those food particles and grow. Bacteria form a sticky film on your teeth, known as plaque. If plaque is not removed and treated, it can form hard deposits called tartar. To remove tartar, you will need to visit your dentist and get a scaling done.

Throat Infections

Sometimes, bad breath comes from somewhere other than the mouth. Infections in the throat like a peritonsillar abscess (Quinsy) can cause bad breath.

Sometimes, bacteria and food particles mix up and form hard stones in your tonsils, known as tonsilloliths, which become a source of bad breath.

Liver Disease
