What Causes Bad Breath?

In order to address bad breath, you need to understand what’s causing it.

Bad breath, we all know what it is and I’m sure we’ve all been embarrassed by our own from time to time. But what causes it?

Knowing and understanding what causes bad breath can help you prevent it and the embarrassment that often accompanies it. Read on to learn more about what causes bad breath and ways in which you can reduce it.


Some of the foods we eat can give us temporary bad breath. Garlic, onions, coffee, spicy or fragrant foods can leave your mouth less than fresh. Brush your teeth, chew sugar-free gum, or try using an alcohol-free mouthwash for freshness.

Dry mouth

Lack of saliva creates dry mouth, which may be a side effect of medications, smoking, or mouth breathing or it could be a symptom of an underlying health concern. Talk to us about dry mouth to find out the best ways to prevent it.

Dental issues

Bad breath can be caused by dental issues such as gum disease or cavities. Crowded teeth or dental appliances that don’t fit correctly can also cause bad breath. See your dentist to for a full checkup to make sure you don’t have any cavities and to rule out any oral care issues you may have.


Without proper brushing, flossing and regular visits to the dentist, bacteria is not being removed correctly from your mouth regularly. The build-up of this sticky bacteria can lead to bad breath. By following the ADA recommendation of brushing twice a day, flossing daily, along with routine visits to the dentist, you can help keep bacteria in check. Cleaning you tongue is also a great way to reduce the bacteria in your mouth.


Sinus infections, tonsillitis, respiratory issues and even diabetes can result in bad breath. Your doctor may prescribe medication for these conditions which may cause dry mouth, which can result in you having bad breath.
