The American Dental Association defines bad breath, or halitosis, as a foul smell that brushing or mints or mouthwash can’t take care of.

Halitosis can be occasional or chronic, and is caused by a number of different factors, like eating habits, oral hygiene and oral diseases.

If the unpleasant smell doesn’t go away for a long time, then it’s recommended to see a dentist about it as soon as possible. Here are some things that could be causing it:


More often than not, smells associated with the mouth are connected to the food you eat. Food items like garlic and onion leave a specific odor in the mouth, which can linger for a short while.

Sometimes, bits and pieces from the food you eat may get stuck between your teeth, which can lead to plaque buildup and bacteria growth. This is another cause of bad breath. Ketogenic meals may also cause ketone breath. These foods burn fat and make ketones as an end-product, giving your breath a fruity odor.


Smoking leaves behind a characteristic smell on your body and in your mouth. This smell may linger on for hours, giving smokers a characteristic scent that we all know well. In addition to bad breath, smoking can also lead to a bunch of other oral health issues, like gum disease and oral cancer.

Dry Mouth

Bad breath can also be caused by dry mouth, or xerostomia. The saliva in the mouth keeps it moistened and helps cleanse it. So if the salivary glands in your body are unable to produce enough saliva, this can result in a bad smell. Dry mouth can also lead to other dental problems, like tooth decay, because saliva helps neutralize the acids that cause cavities.

Dentures and Braces

Just like how food particles getting stuck in your teeth can lead to bad breath, particles that get stuck in your braces can also have the same effect. If these food particles aren’t cleaned from your braces or dentures, they may start to rot and cause bad breath. Besides that, if the dentures are not fitted tightly and properly, then that may cause infections and sores which may, in turn, also give rise to bad breath.

Bad breath can also result in other health problems, like sinus infections, colds, sore throats, etc. Whatever the cause, it’s important to get it sorted before the underlying reason develops into a more serious concern. If you feel like your bad breath isn’t going away, you should see a professional dentist.
