What happens if you don't pull it?
How much do you know about wisdom teeth?
Let's take a look
01
The past and present lives of the Little Devil of Wisdom Teeth
Director Fu: 3.4 million years ago, wisdom teeth looked relatively normal, but the mandible was relatively large, and the food was relatively rough at that time, and the wide bite force helped to chew and bite, and it could also fully accommodate the wisdom teeth.
Later, after ancient humans would use fire, they ate some food softly, and wisdom teeth also evolved, the bite force was smaller, the teeth and tooth bones were not used, the mandible slowly atrophied, there was not enough space to accommodate the teeth, resulting in wisdom teeth having no place to grow. Rather than saying that wisdom teeth have evolved, it is better to say that we humans have to slowly evolve wisdom teeth, so now some people do not grow wisdom teeth, which is the evolution process of wisdom teeth.
02
How many wisdom teeth do you have?
Director Fu: Normal people have 28 teeth plus 4 wisdom teeth, one on the left and right, a total of 32 teeth, some people have evolved wisdom teeth, some people have 4 wisdom teeth, some people have 3, and very few people have more than 4, which is a very normal phenomenon.
In addition to the large difference in quantity, there is also a difference in age, some people before the age of 20, all the wisdom teeth have grown out, some people are forty or fifty years old, and even some people are not long for life, which is also a normal phenomenon.
Health tips: Why do wisdom teeth love inflammation?
Director Guo :
1. I can't brush my teeth when I brush my teeth.
2, the position of wisdom teeth is difficult to grow straight, because the mandible is relatively small, there is no place to grow, it is easy to stuff food, grow bacteria, resulting in inflammation.
03
Wisdom teeth also have a role to play
Director Fu: If the front teeth rot and need to be extracted, then at this time the wisdom teeth can be used as a base teeth, hanging a hook to hang both sides, and then assisting the next teeth to repair the missing teeth.
If the non-adjacent tooth is rotten, the wisdom teeth can also be used as a replacement tooth, which we call autologous tooth reimplantation, that is, the wisdom tooth is transplanted to the missing position.
04
These types of wisdom teeth must be removed
(Wisdom teeth under X-ray)
Director Fu: Through X-rays we can see:
The last tooth is a wisdom tooth, which is perpendicular to the tooth next to it.
The second picture The last wisdom tooth grows upside down, the position of the tooth embryo is relatively high, the head is just down, and the people call it upside down.
The third figure the wisdom teeth have completely grown to the front.
Fourth figure Two wisdom teeth pressed against the length.
Although wisdom teeth have a certain role, the above types of wisdom teeth must be pulled out, and will often be inflamed and affect our lives.

How to relieve toothache after tooth extraction?
1 Learn to use medicine after surgery to promote wound healing and prevent postoperative infection.
2 Use an ice pack to relieve the pain after tooth extraction, wrap the ice pack with a gauze, put it on the face, gently put it for a few minutes and then remove it, you can relieve some pain.
3 It is not recommended to brush and rinse your mouth immediately within 24 hours after tooth extraction, pay attention to colder or softer foods, and try not to chew on the side of the tooth extraction.
06
Correct mastery of Pap brushing
Place the toothbrush at an angle of 45 degrees, at the junction of the teeth and gums, and gently tremble.
Every tooth surface is brushed, bacteria survive on every side of the tooth, and the tongue is also the focus area for bacteria to remain.
Brush your teeth twice a day for a minimum of 2 minutes.
