If the teeth are crowded, we should consider tooth extraction correction, usually symmetrical tooth extraction. You don't have to worry about four opinions at ordinary times, and there won't be any problems you worry about. If the gap between teeth is pulled out, the gap will be closed during the correction process; Then, after correcting the teeth, you need to wear the retainer for about half a year to prevent the teeth from rebounding.

Generally, the teeth pulled out by orthodontics are really the two teeth behind the fangs (tiger teeth), which are called bicuspids.

Extraction of wisdom teeth can prevent them from pushing the dentition forward, but it is not big for the already crowded dentition. It is only removed during orthodontic treatment before eruption to maintain the stability of orthodontic treatment.

The first four teeth with crowded teeth have to find adjustment space in front because the space is not prominent enough. Morphologically, we can see the transition from premolar to molar. Generally, it has little effect on chewing function and face after tooth extraction.
