I got my lower wisdom tooth removed six days ago. So much bone had to be removed to get the tooth out. I initially thought the swelling didn't go down and that's why it's still paining when it shouldn't. But when I checked it, there is a very painful hard mass inside my cheeks surrounding my extraction site. It's very painful and the pain has radiated to my ear and temple on the same side. I don't have fever or pus draining issue. What could it be? Is it an infection or an abscess? It's not responding to painkillers as well. And today, I also saw small white stuff inside my cheeks and on the extraction site. My socket doesn't look empty. It's filled with gum. So, I don't understand what is the issue.
