What Causes Bad Breath

Bad breath, or halitosis, is a common issue that can be embarrassing and tough to deal with. But don’t worry, you’re not alone. In fact, according to the American Dental Association, around 80 million people suffer from chronic bad breath. Fortunately, there are several methods for treating this common condition. Read on to discover what they are!

Causes of Bad Breath

When it comes to eliminating bad breath, you first have to identify the cause. Here are some of the most common causes of bad breath:


The most common cause of bad breath is food. When you eat, particles of food get stuck in your teeth and start to decompose. This process releases foul-smelling gases that can cause bad breath.


Tobacco use is another common cause of bad breath. Cigarettes, cigars, and chewing tobacco all contain nicotine and tar, which can dry out your mouth and lead to bad breath.

Dental Issues

If you have poor oral hygiene, food particles and bacteria can build up on your teeth and cause bad breath. If you have gum disease, your gums may be inflamed and bleed easily, which can also cause bad breath.


Bacteria are microscopic organisms that live in your mouth and on your tongue. What many might not realize is that bacteria release foul-smelling gases as they break down food particles.

Dry Mouth

Dry mouth is another common cause of bad breath. When your mouth is dry, there is less saliva to rinse away food particles and bacteria. This can lead to bad breath.


If you have a respiratory infection or sinus infection, mucus can build up in your nose and throat and cause bad breath. If you have GERD, stomach acid can back up into your throat and cause bad breath. If you have diabetes, your body may produce ketones, which can cause bad breath.

How to Get Rid of Bad Breath

The good news is that there are some simple steps you can take to freshen your breath and reduce the likelihood of bad breath. Here are some tips on how to get rid of bad breath:

  • Brush and floss your teeth regularly. This is the most important step in preventing bad breath. Be sure to brush your tongue as well, as bacteria can accumulate there and cause bad breath.
  • Use mouthwash. Mouthwashes can help freshen your breath and kill bacteria that cause bad breath.
  • Avoid foods that cause bad breath. Some foods, such as garlic and onions, can cause bad breath. If you eat these foods, be sure to brush your teeth afterwards.
  • See your dentist regularly. Your dentist can identify any dental problems that may be causing bad breath. Additionally, they can provide you with tips on how to improve your oral hygiene routine.

Following these tips can help you get rid of bad breath and keep your mouth healthy. If you have persistent bad breath, you should see your dentist to rule out any underlying dental or medical problems.
