Hello everyone, I am He Jianliang, the great white tooth king. I am very happy to meet you again!
Some time ago, a friend invited me to answer [what kind of experience is tooth washing] in Zhihu. I saw a very interesting answer inside:

The whole process of tooth washing was described in the most concise words.
As a dentist, I have read a lot of [patient experience articles], and I have gained quite a lot: everyone’s fear of tooth washing mainly comes from pain and sound.
As an enthusiastic netizen, I also share it with you here. In order to make everyone understand the process of tooth washing better, I decided to use a tooth with a lot of calculus to make an external demonstration, which is easier to understand.
What does dental calculus look like?
First of all, let’s watch a tooth pulled out due to severe periodontitis.
High-energy early warning ahead
Please put down your food
This is a tooth with a lot of calculus attached to it.

You can see all sides of this tooth, from the occlusal surface to its front, back, left and right sides. The red, green and gray [stones] on it are dental calculus (some may also be caries or plaque or food residue).
There is no way to remove your teeth by brushing. Is there any other way?
Mouthwash? No!
Floss? No!
In fact, there is only one method, and that is tooth washing. We continue to do this experiment, using this [dirty] tooth to simulate the main process of tooth washing in vitro.
Principle of tooth cleaning
At present, tooth washing is generally carried out by ultrasonic equipment.
Its principle is actually very simple, that is, high-frequency vibration is used to shake off dental calculus on the tooth surface. At the same time of vibration, water will be sprayed to cool down and avoid local temperature being too high.
You see, if we gently touch and slide this metal tip on the surface of the dental calculus, the dental calculus will fall.
Earthquake, Earthquake, Earthquake
Continue to shake
Be crowned with success

This is the washed tooth, and the row of [stones] on the right is part of the dental calculus that fell from this tooth.
After ultrasonic tooth cleaning is completed, some doctors will also use hand-used instruments for local supplementary scraping.
Then there is the smooth surface of the teeth.
After the dental calculus on the tooth surface, which was previously licked smooth by the tongue, falls off, the tooth surface may lick very rough. We use polishing instruments to finish the teeth, so that the teeth will take on a new look!

Is it true that tooth washing is done with medicine and water?
There is a misunderstanding that tooth washing is done with medicine and water. Based on the stereotype of “three drugs are poisonous”, it is believed that too much use will harm the health of teeth and oral cavity.
In fact, the water used in tooth washing is pure water, which is used to cool down, not liquid medicine.
After tooth washing, doctors usually use hydrogen peroxide to wash periodontal tissue to wash away the debris of dental calculus that has fallen.
However, some gingival inflammation is severe, and they really use drugs, but that is also for the auxiliary control of local inflammation. These so-called drugs or potions only play an auxiliary role in the tooth washing process, not the meaning of the word “washing” itself.
Does washing your teeth hurt your teeth?
Some people will say: Ultrasonic tooth cleaning can easily shatter dental calculi, and will it also shatter teeth?
In fact, although dental calculus is very hard, it is very loose and brittle compared with teeth.
Moreover, the combination of dental calculus and teeth is relatively loose, so that dental calculus can be knocked off the tooth surface without damaging the enamel on the tooth surface.
Therefore, we said: What we wash off is not the teeth themselves, but the dental calculus that adheres to the surface of the teeth-dirty things that do not belong to us.
Does it hurt to wash teeth?
If you haven’t washed your teeth once in ten years, this washing is likely to cause great pain and massive bleeding, causing rare dental psychological shadow to you. Of course, if the pain is severe, you can use anesthetic to wash your teeth (although it is rare).
However, if there are not so many dental calculi washed and cleaned every year, it will feel a little sour and refreshing at most and will not cause unbearable pain.
Therefore, to sum up, it is refreshing to wash teeth for a while, and it is always refreshing to wash teeth every year!
