Tooth extraction is not necessary to correct teeth. Whether tooth extraction is needed in the process of correction depends mainly on the specific deformity of the patient's teeth. If the tooth deformity is caused by overcrowded teeth, then in order to align the teeth, sometimes tooth extraction is chosen. If the patient's tooth deformity is not very serious, the ideal correction effect can be achieved by wearing dental appliances. In this case, doctors generally do not choose tooth extraction, because there are many problems involved after tooth extraction, which is not conducive to orthodontics.

If patients need to have their teeth extracted during the process of correcting their teeth, doctors will try to choose unhealthy teeth for tooth extraction. Before tooth extraction, the doctor will comprehensively consider the patient's entire oral teeth and decide which tooth to pull out.
