1 week after wisdom teeth removal, I am feeling extremely dry on the area of removal. Is this normal?

I had my four wisdom teeth removed one week ago. Everything was doing fine but the past two days in the wisdom teeth area it has been extremely dry. Nothing I have done has made the dry feeling go away. There has also been continuing jaw pain and soreness. The stitches are not on top my the surface of my molars but on the back side due to my teeth being impacted and caught under my molars.
