It depends on the size of the tooth extraction wound. Like the big teeth at the back, especially the wisdom teeth, because of the different conditions of the teeth, sometimes the wounds will be larger after tooth extraction and need to be stitched. But don't worry, as long as you find a regular stomatology department now, the tooth extraction will be painless and the suture will not be uncomfortable, just to make your wound grow faster, and the stitches can be removed in a few days.
