I had that exact same thing happen. My wisdom tooth got infected and I was miserable so my dentist (who was an awesome dentist) pulled it out instead of making me wait for a spot at the oral surgeon's to open up.
Well a few months later my tooth started to hurt where there was no tooth! I thought I was going crazy but my dentist took one look and the next thing I knew he asked his assistant for a "10 blade."
I did feel MUCH better 24 hours later when the tiny piece of bone that had broken off was safely removed.
