Ms Liu: I am 24 years old. My teeth are irregular and I want to correct them. But the doctor said that two wisdom teeth should be pulled out. I'm afraid other teeth will loosen after extraction. What should I do? Shi Yang, Director of Orthodontics Department of Zhengzhou Stomatological Hospital: In the orthodontic clinic, there are often patients who worry that the removal of wisdom teeth will loosen other teeth, or think that wisdom teeth will not hurt if they don't grow out, and they don't need treatment or extraction. First of all, it is certain that the removal of wisdom teeth will not affect the loosening of other teeth. There is a simple reason. No matter whether the tooth is pulled out or not, there is always the last tooth in the mouth. In addition, the posterior teeth are basically inclined forward. In other words, the back teeth depend on the front teeth, so there is no need to worry that the loss of wisdom teeth will lead to the loosening of other teeth. Secondly, wisdom depends on development. ① wisdom teeth that erupt normally have a good occlusal relationship and can be preserved; ② Wisdom teeth erupt, but it is not good for the jaw, and the maxilla is more common on the buccal side. In most cases, it is impossible to establish a good jaw, and biting the mucosa is easy to cause ulcers. It is recommended to remove it. ③ Wisdom teeth can't erupt normally (impacted). This type of tooth is usually buried in alveolar bone. If there is pain, even if it is not corrected, the tooth should be pulled out. (4) there is no bite. In this case, wisdom teeth sometimes erupt excessively, which will affect occlusion and cause damage to temporomandibular joint. It is recommended to remove it. Finally, the overall design requirements should be considered in orthodontic diagnosis. Therefore, orthodontic wisdom tooth extraction should be analyzed according to everyone's situation and specific problems. It is recommended to listen to the opinions of orthodontists in regular hospitals.
