What effect does tooth extraction have on teeth?
The purpose of orthodontics and tooth extraction is only to provide an aligned gap for non-crowded teeth and an inward retraction gap for protruding teeth. Every tooth in the mouth has different functions and different importance.

Doctors should choose relatively unimportant tooth extraction that can solve the problem. Sometimes, in order to prevent the midline deviation, after the right tooth is pulled out, the left tooth should be pulled out symmetrically; After maxillary tooth extraction, sometimes in order to establish a normal relationship between upper and lower teeth, mandibular teeth sometimes need compensatory tooth extraction. Of course, sometimes two or three teeth may be pulled out according to the actual situation of the patient.

Some scholars have proved that the extraction of some teeth has no obvious effect on chewing function. After tooth extraction, the teeth can reach the ideal arrangement after correction, which will improve rather than hinder health. Tooth extraction is usually carried out according to the patient's condition. First pull out the wisdom teeth, and then pull out the second premolar according to the situation. Compared with other teeth, the oral function of the second premolar has little effect, and it can generally be extracted with little effect.
