5 Things That Trigger Bad Breath

We’ve all experienced bad breath at some point. And it can be very embarrassing when it happens. But, there are some things you can look out for if you want to avoid bad breath problems.

Here are five things that can help trigger bad breath:

Poor Dental Habits

This is probably the biggest cause of bad breath.

According to the American Dental Association, bad breath starts in the mouth. If you don’t have good oral hygiene, it allows food particles to collect on the surface of the tongue, between your teeth and around your gums.

The naturally occurring bacteria in your mouth then break down these food particles and release chemicals with a strong odor, which affects your breath.


This is another common cause of bad breath. Specifically, foods like garlic and onions can make your breath smell foul.

According to the American Dental Association, once your food is digested, chemicals that cause odors can be absorbed in your bloodstream and be sent to your lungs, meaning they will be released when you breath out.

So, the odor from these types of foods can stick with you long after eating!

Lack of Saliva

The American Dental Association says that saliva helps wash food particles away from your mouth. On top of this, saliva helps neutralize acids produced by plaque and wash away dead cells that accumulate on the tongue, cheeks and gums, all of which can contribute to bad breath.

Therefore, those who have a dry mouth are more likely to experience bad breath.


On top of staining your teeth and irritating your gums, smoking and chewing tobacco based products can cause bad breath, says WebMD.

Smoking also causes a dry mouth, further contributing to bad breath.


According to the American Dental Association, infections of the mouth can also contribute to bad breath. This includes things like tooth decay, mouth sores, gum disease and surgical wounds.

What You Can Do

The American Dental Association says the best weapon you have against bad breath is good oral hygiene.

So, make sure you are brushing your teeth twice a day, flossing once a day and visiting your dentist regularly!
