Maybe
You've also encountered situations like this
……
After a tooth removal one day
On a whim, I sniffed the toothpick
As a result, he was so stinky that he wanted to die on the spot
Sometimes the finger accidentally touches the tooth
Fingertips have a long lingering lingering aftertaste
The top note is thick, the heart note is sour, and the back note is a bit top-notch
Wake up from a nap in the company
Awkwardly looking at the spit that flowed down from himself
Take a closer look
He even began to suspect that he was eating durian stewed at noon
"Obviously I don't have bad breath,
Brushed my teeth in the morning,
Why is that? ”
That's because
We ate a wide variety of food
The mouth will always leave a little residue
Plus from time to time a little bit of epithelial cells are shed
Patients with gingivitis and periodontitis have a little more blood
Make our mouth
It's almost like a miniature dump
Why?
Similar to the principle that garbage will become smelly after a long time
In our mouth
There is also a large microbiota
Led by Gram-negative anaerobic bacteria
They eat garbage on the side
On the one hand, a large number of volatile sulfides are produced
This is one of the main sources of bad breath[1]
Even if we usually brush our teeth seriously
The rate of reproduction of bacteria is also beyond everyone's imagination
moreover
Without systematic brushing training
There is a high probability that there will be a hygienic dead end when brushing your teeth
For example, the deepest molars are often difficult to brush
Food residue is also often left between the teeth
Besides
It still exists in the mouth
Can't be easily brushed away with a toothbrush —
"Anti-brush" big three
First of all, let's talk about the old friend that everyone is most familiar with- caries
On our teeth
There are many "tribes" of bacteria - plaque
These bacteria like to eat sugar and starch
A large amount of acidic substances is then produced
Plaque cannot be washed away by running water
It can only be removed by mechanical means
(e.g. brushing, flossing and ultrasonic scaling)
If not removed in time
Acids can constantly corrode teeth
in time
The tooth will be corroded out of a hole[2]
This tooth hole is a great food warehouse for bacteria
They're in this hole
Constantly decaying fermentation...
The smell is naturally sour
Let's look at the dental stones that everyone hates
In the bacterial tribe of the oral cavity
There is a "nanobacterium"[3]
It is a special microorganism that allows the body to form stones
(Of course, some say they are not creatures.)
Under the "nourishment" of saliva and gingival fluid
As a mineralization center
Invite food scraps
Calcium salts in oral fluid
As well as shedding epithelial cells involved
Everyone hugged each other
Blend with each other, not separate from each other
Over time, calculus stones adhere to the teeth
Dental calculus pressing on the gums
Not only does it damage periodontal health
It also gives off a "charming" smell...
In addition, there is another friend who may not be so familiar with it - tonsil stones
tonsil
As part of the body's immune system
Helps the body fight infections
It is named after the almond-like shape
It has many small nests on its surface
If the tonsils are inflamed for a long time
Inability to secrete fluid in time
Wash away the "garbage" in the nest
in time
Stones can also form
Thus producing oral odor[4]
In general, I want to prevent the mouth from becoming a garbage dump
The easiest and most straightforward way, of course, is this
Get rid of the garbage in time!
That is, brush your teeth more!
Brush your teeth the right way!
Conditional
Brush it every time you finish eating
Unconditional
It is also possible to gargle with water or mouthwash
You can also use floss instead of a toothpick
Remove food debris from between teeth in a timely manner
In addition, it is highly recommended that you must clean your teeth regularly
High-frequency oscillations produced by ultrasonic waves
Remove plaque and calculus from the surface of the teeth
This will not only get rid of bad breath
It can also effectively prevent oral diseases such as caries and periodontitis
Finally, I wish everyone a good tooth
Say goodbye to bad breath
