A week ago, I got my right side pre molar extracted in order to get braces. And got left side pre molar extracted 4 days ago. The left side is doing just fine . My issue is that the molar next to the extraction side of the right side pre molar still hurts even after a week. Its hurts when I bite and apply pressure to it. I am very worried since I've never had this kind of toothache. What can be the problem?
