What is Halitosis/Bad Breath?

Halitosis is a medical condition that causes bad breath. It is often called bad breath.

The condition affects 25 percent of the human population, with 1 in 4 people believed to suffer from the condition. As the main reason for a third of the dental visits, coming in after tooth decay and gum disease, it calls for attention.

How does one get halitosis?

Halitosis often originates from the gums or the tongue.

Yes, you brushed your teeth this morning, and you’ll do the same this evening but, you might still have bad breath. Why is that? Well, the bad odor in the mouth comes from waste caused by bacteria in the mouth, as well as the decay of food particles, poor oral hygiene, and even food debris in the mouth. The debris and decay, plus the bacterial action cause the production of sulfur compounds which are responsible for the stinking breath.

If that is the case, why don’t fresh breath mints and mouthwashes help?

Well, some cases of bad breath result from medical issues like infections. Well, infections, diabetes, liver malfunctions, and kidney failure have been known to manifest through bad breath.

Could there be other causes of bad breath?

Yes. Bad breath could result from:

Tobacco smoking which causes bad breath, while increasing your risk of gum disease.


Some foods like garlic and onion can cause bad breath because their breakdown forms stinky gases.

Dry mouth

Diseases like xerostomia dry out the mouth. Since saliva cleans the mouth, its absence causes a buildup of odors.

Poor dental hygiene

As mentioned above, food residue can cause halitosis. What we didn’t mention is that a film of bacteria, plaque, builds up if you don’t brush and floss well. Plaque causes irritation of the gum and the teeth causing an inflammation, which results in periodontitis. The result is bad breath.


Some medications will reduce the production of saliva, increasing odor. And, other drugs will stink as they break down and release chemicals in your breath. Chemotherapy chemicals, nitrates, and vitamins supplements can also cause bad breath.

Crash diets

You didn’t see this one coming, did you? Well, the low-carb dieting programs you are thinking about can cause bad breath because of the production of ketones from the breakdown of fats.

Foreign bodies

Bad breath from a foreign body could get stuck up the nasal cavity causing bad breath.

Mouth, throat, and nose conditions

Wondering how this is possible? Well, in some cases, some small, bacteria-covered stones can form on your tonsils at the back of the throat, leading to the production of odor. At the same time, an infection or an inflammation of the sinuses, the throat, mouth or the nose can cause halitosis.

So, you don’t fall into any of these categories? Perhaps you have a rare cause of bad breath like:

  • Bowel obstruction
