Tooth extraction means that the wound has not healed, or the correction has not closed the gap. If the wound doesn't grow well, we should consider whether there are residual roots in it that will affect the wound healing. If there are residual roots, pull them out as soon as possible, and the wound will grow well after pulling them out. If the correction fails to close the gap, it means that the correction has not been successful, and the gap must be completely closed, so that there is no gap, because if there is a gap, the teeth will shift and affect other teeth. I suggest you see a doctor. If you don't correct it well, you should continue to correct your teeth.
