I've seen a doctor before I asked the question here, and he checked my ear and didn't find anything wrong with it. The aches have almost completely disappeared in the last few days. I called my dentist and asked if they have a record of my treatments, but they don't, and I really can't remember which of my wisdom teeth are still there. I think I'll just wait and see if the pain comes back, and if it does I'll see my dentist.
