What are some good ways to self-diagnose bad breath?

Sometimes you have bad breath but don't notice it, which is quite embarrassing. Often you feel pretty good about yourself, and it's embarrassing to be in an interpersonal relationship. So, self-testing for bad breath in daily interpersonal relationships can also avoid embarrassing situations. The self-testing method is relatively simple. For example, put your palm in front of your mouth and exhale. If you have bad breath, you will be able to smell it.

What are some good ways to self-diagnose bad breath?

1. Self-examination method:

This is the simplest method. Cover your mouth and nose with your hands, exhale through your mouth, and smell your nose to see if there is any peculiar smell in your breath. However, this method may not work for people with rhinitis or poor sense of smell. Sometimes, if you have a cold or a stuffy nose, this method will not work.

2. Listen to people’s feedback:

If the above method doesn't work, you can go find someone close to you, such as relatives and friends. You don't have to be too cautious in front of these people. Some people may be more reserved and will not say anything even if there is a peculiar smell. So just be frank and ask them directly.

3. Wrist licking test:

Breath odor is related to saliva because there is an enzyme in saliva. Therefore, we can lick the inside of our wrist or the back of our hand, and then smell it after it dries. This way we can determine whether our breath is fresh.

4. Plastic spoon test method:

The wrist licking method can also be tested with the help of other objects, such as the plastic spoon test. The method is basically the same as the wrist licking test. Both fall within the scope of clinical testing and will not be elaborated on.

5. Physician's nose test:

Find a professional dentist to determine whether you have bad breath through direct nasal testing. This is also a relatively easy to perform and relatively accurate method. The degree of bad breath can be quantified by scoring.

6. Chemical testing method:

The experimental testing method is more complicated and professional because it requires the use of chemical knowledge for evaluation. Most people really can't do it. You can search online for specific operations, such as microbial and fungal testing, saliva culture, etc.

7. Artificial nose test method:

This method requires some professional instruments to test. The method is relatively simple and easy to operate. It uses the principle of chemical reaction to digitally represent the ppb concentration of H2S in the oral cavity to determine the degree of bad breath.
