Yeah go back and get it check out you might have a dry pocket.
I have had my wisdom teeth pulled and I was in pain for about 2 weeks then when I went back I was told because of the hole where the tooth was I had a piece of food in there.
Which I found kind of strange because I would bruch and rinse my out after eating.
You might have a piece of food in there also.
If it's getting worse, I would go back and have them check for a dry socket. Usually the pain from an extraction will get better over time. If it all of a sudden gets worse, we always tell patients they may have a dry socket which is most common when lower wisdom teeth are extracted. It may feel like the upper jaw but this may be referred pain. I would have it checked out because they can pack some medicine in there to help it feel better.
