Tooth extraction rarely leads to facial depression. What we are talking about here is the general situation, that is, there are special circumstances. If wisdom teeth are pulled out, or one or two teeth of the back teeth are pulled out, there will be no facial depression after pulling out. If the front fangs, that is, tiger teeth, are pulled out, it may cause facial depression after tiger teeth are pulled out. Because the tiger tooth plays a role in supporting the corners of the mouth, the corners of the mouth collapse after the tiger tooth is pulled out, so that the face will appear sunken. If multiple teeth are pulled out and false teeth are not made in time, there may be facial depression after a long time.
