Post nasal drip is a condition that occurs when there is excessive mucus produced by the nasal mucosa. This mucus collects in your throat causing bad breath. Bad breath is usually caused by the anaerobic bacteria that reside in the throat coming into contact with food debris, post nasal drip or saliva. When you have an allergy, mucus starts sliding to the back of the throat instead of dripping out through the nose. As a result, the bacteria are covered in mucus causing post nasal drip bad breath.

Why Does Post Nasal Drip Cause Bad Breath?

One of the most common causes of bad breath is post nasal drip. The bacteria in your throat feed on the mucus secretions from your throat and nose. This is what causes bad breath. If you suffer from sinusitis, you should be wary of dairy products such as cheese, yoghurt and milk. These can cause the mucus to thicken and exacerbate the condition. In some cases, the condition can produce a yellow or white film on the tongue. You will feel like you constantly have something stuck in your throat and might need to clear your throat frequently.

What Can I Do About It?



Your doctor will prescribe medication to help dry up your sinuses and prevent the buildup of mucus. It is important for your doctor to take care not to prescribe antihistamines that will cause dry mouth. Dry mouth can also cause bad breath since it creates an anaerobic environment. This creates the perfect environment for bacteria to produce Volatile Sulfur Compounds. Be wary of using antihistamines too frequently as they can be addictive.


Irrigate Your Nose

Devices like a sinus irrigator can be used to flush the sinuses whenever they’re clogged. This is one of the most effective ways of combating post nasal drip bad breath and controlling sinus infections. They help to bring back ciliary function to normal and get rid of bad breath caused by post nasal drip. You will be back to your normal self within a short period of using the devise regularly.


Try Nasal Sinus Drops

Squeeze the amount of drops as indicated into each of your nostrils and inhale to move the drops through the sinuses (if necessary). They help eliminate bad breath by stopping the production of sulfur compounds produced when bacteria and mucus combine.


Other Remedies for Bad Breath

  • Make a point of brushing your teeth twice every day. You should also floss at least once a day to fight bad breath. This not only keeps your teeth clean, it also reduces bacteria. Clean your tongue properly using a scraper as it is covered with tiny hairs that trap bacteria. Visit your dentist for cleaning at least twice per year.

  • Saliva helps a great deal in cleaning the mouth and removing particles that can cause bad odor. Lack of saliva can therefore lead to bad breath. If you mouth is feeling kind of dry, take lots of water, suck sugarless logenzes or chew sugarless gum.

  • Quit smoking as it cases havoc with your overall health and your breath.

It is important to consult your doctor about your bad breath as it could be a symptom of an underlying medical condition.

What Others Have Experienced

“I have been having this putrid poo smell from my mouth for a while now and yet I brush my teeth twice a day and floss regularly. The smell won’t go away despite my great oral hygiene. It is so bad that am embarrassed to ask family and friends whether my breath stinks. I’ve become reclusive as a result of this situation. Finally went to the doc and he prescribed some meds as well sinus drops. Also keep irrigating my nose 1-2 times a day and the condition is much better now.”

“I discovered that my post nasal drip bad breath was caused by chronic sinus infections. I’d use antibiotics and the bad breath would go away. However, it would come back within a few days. I found out about biofilms and discovered that a nasal irrigator could help. I used one along with saline water to eliminate the bacteria. I couldn’t believe how fast it worked. Within a few days the post nasal drip had improved drastically and the tongue coating had disappeared. However, it was not totally eliminated. Finally I took half an amoxicillin tab and mixed it with the solution I had used previously with the nasal pulastor. This worked like a charm.”

“I have eliminated all high fat and dairy products from my diet but haven’t seen an improvement in my condition. My breath stinks to the high heavens. I assumed my post nasal drip was as a result of chronic sinus infection, but couldn’t figure out how this was possible since I have tried every trick in the book to get rid of it.”
