(1) Arrange the crowded teeth by using the extraction gap. Patients with crowding degree II-III are more likely to have their teeth extracted.
(2) Retract the anterior teeth between tooth extraction, improve the protrusion of dental arch and improve the face shape. For example, some people have protruding lips. After tooth extraction, the protrusion of lips will become smaller and the face will become beautiful.
(3) The occlusal relationship of the posterior teeth is adjusted by the extraction interval, so that the posterior teeth are staggered and the occlusal contact area is the largest, and the best chewing efficiency is achieved.
When you go to the dentist, you often hear the doctor say that you have a wisdom tooth that needs to be pulled out. It's best to pull it out as soon as possible. Many people think my teeth are fine, so why bother? This idea is both right and wrong. The right thing is that teeth can't be pulled out casually, but the wrong thing is that doctors think that wisdom teeth that should be pulled out should be pulled out as soon as possible.
Why do you have to pull out wisdom teeth?
From the first tooth in the middle of the dentition, the eighth tooth is the wisdom tooth.
Modern people's diet is getting more and more elaborate, the mandible is underdeveloped, and the length of the mandible is insufficient. Most wisdom teeth can't erupt completely, or the eruption position is not correct, or they are completely embedded in the bone. The dentist called this tooth an impacted tooth.
Because of the abnormal position, direction and height of eruption, wisdom teeth usually do not have chewing function, and are easy to bite buccal mucosa and opposite gingiva, which often causes food impaction, inflammation, swelling and pain of surrounding soft tissues, leading to periodontal tissue destruction.
Wisdom teeth are located in the last part of the mouth, and the space is narrow, the toothbrush is not easy to reach, the sanitary conditions are poor, and it is easy to cause dental caries, and it is also easy to cause dental caries of the adjacent teeth in front.
Under the condition that the jaw bone is not fully developed and there is not enough space, wisdom teeth erupt forcibly, squeezing the front teeth, sometimes causing inexplicable pain, and can also cause the roots of the front teeth to be compressed and absorbed, and even cause the front dentition to be distorted, which will aggravate the uneven dentition.
The abnormal eruption position, height and direction of wisdom teeth interfere with the normal movement of jaw during chewing, which causes abnormal forces on masticatory muscles and temporomandibular joint, causing spasm and pain of related muscles, which may lead to abnormal function of temporomandibular joint and even pathological changes of joint structure for a long time.
Of course, wisdom teeth that erupt normally and have chewing function should be preserved and protected. In addition, wisdom teeth that are completely ambushed and have no symptoms can also be preserved. However, the existence of wisdom teeth reduces the fracture resistance of mandible. For people engaged in acrobatics or violent collision and contact sports, in order to prevent mandibular fracture, it is best to remove the fully buried wisdom teeth in advance.
In order to protect oral health, dentists often suggest that wisdom teeth be removed to avoid damage to other teeth and tissues. Especially in your case, in order to meet the needs of orthodontics and ensure the effect of orthodontic treatment, wisdom teeth are usually pulled out.
