What Are the Causes of Bad Breath

causes-of-bad-breathDo you suffer from chronic bad breath? Have you tried all sorts of products such as mouthwashes, toothpaste and others to get rid of it but nothing works?

If so you are not alone. There are millions of people out there who suffer from halitosis. You can be free from it easier than you think, you just need to know what can cause it.

By altering your lifestyle and eating habits a little bit, you can forget this problem forever.

Here are main causes of bad breath.

The Food You Consume

There is nothing new in it that eating garlic, onions, oils and other “smelly” foods can cause odor, especially if we have them raw.

There are two reasons why they cause bad odor in your mouth.

Firstly, the particles of these foods remain between and in your teeth. That can be easily cured by washing your teeth or chewing a gum.

The other way they make your breath smelly is that after the digestion the components of these foods are taken into the blood. With the circulation, they go to the lung and from there they come up when you breathe out.

I do not say to get rid of these foods since they are healthy ones, but reducing the amount you consume will surely help.

Dry Mouth

Has it ever happened to you that you woke up in the morning with a dry mouth because it had been open all night. It is not a comfortable feeling, and the odor of your mouth is pretty bad, isn’t it?

Saliva is essential for the health of your mouth. It cleans it from the food particles, bacteria, dead cells and even support the digestion.

If your mouth is dry, the dead cells gather on your gums, teeth and tongue, and they start to deteriorate that causes bad odor.

The solution is to keep your mouth and body hydrated. Take a bottle of water everywhere.


Infections in your nose and throat can also cause foul smell because of the bacteria and the mucus. After treatment, it usually passes away.


Smoking causes bad odor in your mouth in two ways. Once, the fume makes your mouth foul. Besides, it dehydrates your body and mouth.

On top of that, smokers tend to have gum diseases that also cause smelly breath.

Solution? Giving up smoking is vital for health, but if you cannot at least smoke less. Have chewing gum and keep your mouth hydrated.

Chronic Diseases in Mouth

There are several illnesses that can cause halitosis, mainly the ones in the lung and stomach.

But there are others. For example, kidney problems make you breath smells like urine. Those who suffer from diabetes usually have a fruit-like odor.

If you experience these, turn to your doctor as soon as possible.


Stress has many harmful affects on your body including your digestive system. As it was mentioned before stomach problems can be a reason of bad odor.


Alcohol makes your mouth stinking in several ways. Most of the alcoholic beverages are not odorous, just think about beer. Besides, they dehydrate your mouth, body and affect your digestive system badly.

Personally, whenever I drink something I always have a glass of water after.

Fasting Diets

If you want to lose weight and you follow an extreme diet, that I do not suggest at all, you can also have bad breath. That happens because fatty acids are broken down during fasting. This metabolic process is the ketoacidosis.

Dental Problems

Most of the people suffer from smelly breath because of gum and teeth diseases caused by poor dental hygiene.

Whenever you eat or drink something, the particles will be everywhere in your mouth that are excellent places for bacteria.

The solution is simple. Brush your teeth and use dental floss several times a day. Frequent oral care also prevents dental issues like tooth decay, gingivitis, and plaque.

Diary Products

A lot of people are intolerant to milk products that cause digestive problems. If you are among them, you need to get rid of these and find alternatives.


There are other causes of bad breath: drugs, supplements, mouth or throat cancer, medicines and other chemicals.
