Tooth extraction is just a corrective measure. If tooth extraction can solve the problem of teeth, doctors will not say that tooth extraction is needed. The purpose of tooth extraction is to provide enough clearance for protruding and crowded teeth, and also to adjust the occlusal relationship of teeth. If the gap between teeth is insufficient and the treatment can't achieve good results, then the tooth can only be extracted. So tooth extraction is not necessary for orthodontics.
Extended data
Correcting teeth requires tooth extraction:
1, dentition crowding: small alveolar bone leads to crowded teeth, which cannot accommodate the existing number of teeth.
2, buck teeth: buck teeth, to extract teeth to obtain free backlash, so as to shrink the front teeth back and forth, move forward the rear teeth, and close the backlash.
3. The occlusal relationship needs to be corrected: the upper and lower teeth are asymmetrical, and it is necessary to adjust the occlusal relationship after tooth extraction.
