Bad Breath: Possible Causes You May Not Even Know About

Did you know that over 70% of people who have bad breath don’t even know they do?  Having bad breath is usually harmless, but so embarrassing that no one will tell you about it. Halitosis occurs when naturally occurring bacteria in the mouth breaks down food particles present between your teeth and gum line. This process is what leads to bad breath.

Fortunately, this problem is temporary and can be cured.  The surprising news is that halitosis is caused by other factors other than failing to brush or floss your teeth.

Here are some possible causes you may not even know about.


People on different medication have a dry mouth as a side effect and thus is what leads to bad breath. These medicines include sedatives, antidepressants, antihistamines, and antipsychotics. Saliva is important in getting rid of food particles. When you have less of it, odor increases. All you need is to keep your mouth moist. A dentist can also recommend a product to help treat a dry mouth.

Foods you eat

Foods with strong scents like garlic and onions affects the air you exhale. There are enzymes that aid in digestion once you start chewing food. Once this food is absorbed into the bloodstream, it goes to your lungs and this is what you breathe out. While sucking on mint or brushing may mask your bad breath, it doesn’t fully eliminate this problem. The only solution is to avoid dairy products, spicy, and high-fat foods.

Mouth piercings

Yes, you had it right, that cool and fashionable tongue piercing may provide a haven for harmful bacteria which leads to bad breath. A study conducted shows increased incidences of yeast infections in people with tongue piercings.

Sinus problems

People with nasal congestion can encounter bad breath. This is because a continuous nasal drip forms a regular food source and this could hub unfriendly bacteria and germs. If you have a sinus problem, you need to brush and floss regularly. Using a mouth cleanser also helps to stimulate production of saliva as well as getting rid of unwanted bacteria.

Gum disease

This is probably one of the most popular causes of halitosis and the bad news is that not many people know it. When your gums get infected by oral bacteria, the germs breathe sulfur and this is what leads to your bad breath. The only way to correct this is to visit your dentist who’ll advice on how to get rid of gum disease and ensure that you lead a healthy, normal life.

Poor oral hygiene

If you don’t brush or floss your teeth on a regular basis, you may suffer from halitosis.  Failing to brush means that food residues accumulate and this leads to plaque formation. Plaque provides a breeding ground for the bacteria. Bacteria that feeds on sugars ad plaque expel sulfuric compounds and this can lead to halitosis. Bacteria build up also leads to periodontal disease and cavities which may further leave you with a stinking mouth.

The only solution in this case is to brush and floss your teeth at least twice daily. If you’re looking for the best electric toothbrushes, Toothbrushbest has great reviews of some of the most effective toothbrushes available in the market.


People who smoke, particularly those who smoke cigarettes have a chronic smoker’s breath that emanates from chemicals present in cigarettes. Long-term effects could lead to throat and lung cancer. A study conducted found out that compounds released when one smokes leads to reduced salivary flow, which in turn leads to a dry mouth. A dry mouth creates a haven for bacteria buildup which results in bad breath. In addition, smoking can lead to periodontal disease and you would have to deal with a little more than bad breath. In this case, you need to quit smoking to get rid of the bad breath.

Breathing through your mouth

Every time you breathe through your mouth, you end up cutting down saliva production leading to a dry mouth. That’s why most people wake up with a smelly mouth. Snoring and mouth breathing could indicate other underlying health conditions like sleep apnea and it’s best to visit a doctor for diagnosis.

Low-carb diet

Lately, there’s been a craze about low-carb diets. What happens is that the body turns to proteins and fats for energy since carbohydrates are lacking. However, this leads to production of certain chemicals that cause bad breath. This is not something that you can get rid of by brushing or flossing.

These are some of the reasons you may be having bad breath. Ensure that you visit your dentist. Brush and floss at least twice daily.
