Whether the teeth can be straightened without wisdom teeth extraction needs to be analyzed by a specialist through radiographs and impressions. If the wisdom teeth erupt and bite relationship is normal, they do not need to be extracted. Wisdom teeth need to be extracted if they grow crooked and squeeze the teeth in front of them, affecting the movement of the teeth. After orthodontic treatment of the front teeth, wisdom teeth may need to be extracted because the wisdom teeth that have grown out of alignment may grow forward and cause the corrected teeth to become misaligned again. Due to the design of the orthodontic program, the teeth may need to be moved backward, and if the wisdom teeth grow back crooked, the wisdom teeth may need to be removed first in order to allow the front teeth to move backward. If the orthodontic program design does not address the situation and the wisdom teeth have not grown in crookedly, the wisdom teeth do not necessarily need to be removed during or before the orthodontic procedure. If the wisdom teeth are fully erupted and the upper and lower jaws are in good occlusal relationship, they do not need to be removed. In addition, if the wisdom teeth are crooked, they need to be removed as soon as possible; if they are not crooked, they need to be considered for removal based on the doctor’s decision, and if they are not growing in and painful.
