Causes of Bad Breath Other Than Poor Oral Hygiene

Poor oral hygiene is the leading cause of bad breath, say dental experts. But somehow, your breath refuse to smell stellar even if you brush, floss and gargle with mouthwash on a regular basis. Did you know that aside from poor oral hygiene there are other common causes of bad breath?
In this article, we will talk about some of the things that can leave your breath smelling unpleasant even if you deserve an award for best in oral hygiene.

Prescription Drugs

Some medications prescribed by doctors can be blamed for bad breath, including most especially those whose side effects include mouth dryness. When your mouth is dry, dead cells and food particles accumulate, causing odor-causing bacteria to have a blast — their proliferation can leave your mouth smelling horrid.
Antihistamines, blood pressure medications and antidepressants are some of those that are notorious for causing mouth dryness and ultimately bad breath.


Are you suffering from some sort of an infection? Then don’t be surprised if your breath tends to repel everyone — the ongoing infection can cause your breath to reek due to the presence of lots of microbes.
Expect your breath to smell less than perfect if you have a sore throat. The same is true if you have the common cold or flu. Suffering from an infection of the sinuses (sinusitis) can also leave your breath smelling terrible. Don’t worry because your bad breath will go away on its own once the infection resolves.

Low-Carb Diet

Going for a diet that’s low in carbohydrates in order to lose excess weight can cause you to lose some of your friends. That’s because it is something that can leave you with a reeking breath.
According to experts, it has something to do with the fact that a low-carb diet can cause your body to burn fat in order for your cells to have energy, and the said process causes the release of ketones — they can escape your body via your oral cavity, leaving your breath smelling like ammonia or acetone.


It’s not unlikely for your breath to smell kind of fruity if you are diagnosed with diabetes. Or even if you’re not diagnosed with it and your breath still has that characteristic odor, there is a huge possibility that you are unknowingly suffering from diabetes, most especially if it runs in the family, you are overweight or you have poor eating habits.
The reason why diabetes can cause your breath to smell bad is the same as that of a low-carb diet— ketones that are given off as your body utilizes fat for energy.

Lactose Intolerance

Does your breath smell like sour milk? Then there’s this possibility that milk is the culprit most especially if you have lactose intolerance — your body is incapable of breaking down lactose, a sugar in milk.
And by the way, it’s not just lactose intolerance that can make your breath smell horrendous, but so many other issues that concern the digestive system. Some of them include acid reflux, gastroesophageal reflux disease or GERD, stomach ulcers, irritable bowel syndrome or IBS, and constipation.


Are you aware that your favorite mouthwash can be the one to blame for your persistent bad breath? To know whether or not it’s the culprit, take a look at the list of ingredients. If it contains alcohol, then there is no denying that it’s the one that’s causing you your misery — alcohol can cause mouth dryness that can lead to bad breath.
This does not mean, however, that you should quit using mouthwash. What you need to do is ditch your current one and replace it with something that contains no alcohol. (
