What exactly causes bad breath?

Bad breath is very common nowadays. Most of the patients with bad breath have gingivitis, or the cause of gum disease is related to bad breath. Only after you have determined the specific cause of bad breath and choose the appropriate method of treatment can you ensure that you will not be harmed by bad breath. Let us take a look at the relevant causes of bad breath.

First, we are too accustomed to our own body odor.

Just like we cannot detect some subtle smells in our own bedroom, when guests come or when we come back after a while, we will smell a different smell.

Second, the olfactory organ adapts

When the nose smells a certain special smell for a long time, it will completely adapt to this smell and feel very weak or no sensation at all.

This is the same as when you squat in the toilet for a long time to poop but you don’t feel the stink.

The third is related to facial structure

The soft palate at the back of the mouth is connected to the nasal cavity, so the nose cannot smell the odor produced in the back of the mouth.

So, don’t think that people with bad breath are deliberately making you smell bad. In fact, they just really don’t know it.

How to self-diagnose bad breath

Method 1: Wearing a mask

Prepare a mask, put it on, exhale and then inhale through your nose, and smell the exhaled gas carefully to see if there is any "unpleasant smell". If you are not sure at once, try it a few more times.

Or you can cup your mouth with your hands, exhale, and smell it to see if you have bad breath.

Method 2: Smell the saliva method

Lick the back of your hand with your tongue, put some saliva on your hand, and then smell it. Your nose will tell you the answer.
