It will have an impact. I used to have a round face. After the teeth were corrected, the chin was a little sharp and the face became smaller because four tiger teeth were pulled out for correction. I once met a doctor's case. The doctor said that if he wants to correct his teeth, he must have his teeth pulled out. If he pulls out his teeth, his face will sink. It is conceivable that it will definitely have an impact, but it varies from person to person. Moreover, the effect of tooth extraction will be better, and only after tooth extraction will there be room for other teeth to straighten! It depends on your age and the growth of your teeth.
