Will the hard masses above my jawline on both sides, which I didn't have previous to my wisdom tooth extraction, go away?

Doctor, I had my bottom two impacted wisdom teeth removed, one about a year ago, and the other, 6 months ago. I have a hard mass above my jawline (not quite at the end of the jaw) on both sides, one bigger than the other (the bigger mass on the side that was operated on a year ago), which I didn't have previous to my operation. What are these and will they go away eventually?
