Causes of Bad Breathe and its Solution

Bad breath is a very embarrassing problem encountered by many. Scientifically known as halitosis, this unpleasant odour can strike you periodically or can become a chronic issue. This particularly depends on the cause of your bad breathe. You might be unknown about the fact, but the truth is that millions of bacteria thrive in your mouth, especially behind the tongue and leads to bad breath.

The warm and moist conditions of the mouth are an ideal place for the bacteria to grow. People who follow a strict oral hygiene regimen can stay away from this trouble; but unfortunately it’s not a success story for all if the cause is deep rooted. Let’s check the causes of bad breathe and look forward to get a solution for them –

causes of bad breathe and its solutionMorning Mouth

This is a normal cause for bad breathe early in the morning after a night’s sleep and almost everyone faces this. It is not any unhealthy issue because the saliva that stays in your mouth for night long is not being able to wash away the decaying food and bacteria. The mouth also gets dry and the dead cells stay on the tongue on which the bacteria grow emitting the bad odour. This can be easily washed off when you brush youth teeth and clean the interiors of your mouth well.

Dry Mouth

This is also again a cause of bad breathe when the saliva on the tongue reduces and the cleansing of the mouth is not done properly; apart from the point mentioned above there are also many more causes of dry mouth that can lead to bad breathe. They are dehydration, medicinal side effects (especially of antidepressants), some diseases like Sjögren’s syndrome, and radiotherapy done in neck and head region.

Foods and Drinks

There are certain foods that get into the blood and when breathed out from lungs leave a bad breath. Spicy dishes, alcoholic drinks, garlic, and even some sweets can leave bad breathe in the mouth. This is however a temporary cause and can be avoided by avoiding the food itself.


There are some specific medicines that cause bad breath like the ones for treating nerve problems, insomnia and antidepressants. Some more medicines that are responsible for bad breath are Dimethyl sulfoxide, Betel, Phenothiazines, Chloral hydrate, Amfetamines, Nitrites and nitrates, Disulfiram and some medicines that are used in chemotherapy. Talk to your doctor about this side effect and see if he can arrange some alternative medicine for you.


If you are a non smoker you can easily make out who is a smoker by his breathe; this is even more evident if the person is a chain smoker. Their breathe smells like an ashtray. The cause is of course nicotine which equally smells bad. Smoking can also lead to gum diseases that in turn emits bad breathe.

Fasting and Crash Dieting

When you are fasting or dieting hard; chemicals called ketones are produced due to the breakdown of fats, and these are breathed out giving out bad breath.

Underlying Medical Causes

Often some diseases and underlying medical condition is responsible for bad breathe like sinusitis, a lump (polyp) in the nose, chest related diseases, small objects stuck in nostril can cause a bad smell.


Fish Odour Syndrome (Trimethylaminuria)

A rare medical condition, it brings a typical fishy smell in the breath. When the body is unable to break down trimethylamine, found in certain foods, it starts getting released in urine, breathe and sweat.

Bad breathe can be ruled out easily if you can strike out the right cause behind it; more often it’s a build-up of bacteria in the mouth but its recommended to visit a doctor for the right diagnosis if it persists for more than a month.
