I had an infected wisdom tooth 3 weeks ago. I went to the dentist as my upper right 8 tooth is partially erupted and the gym was very red and swollen. I couldn't sleep for 2 days because of the pain. The first dentist who saw me looked and then burst the ulcer with a probe and got me to rinse. He didn't do anything else for me. My mouth continued to hurt on the inside for the next week but then the pain suddenly left the inside of my mouth and I began to get swelling on that side of my face and the pain was gone. I revisited the dentist and saw a different one this time who said it sounded like the infection had spread. She took an X Ray and prescribed me metronizadole for 5 days. The swelling and pain left once I finished the course but now 2 weeks later the pain on that side of my face has returned and a little swelling where it was before. It's not really painful just tingles and feels uncomfortable. I've also had earache/burning in my right ear as well as a painful neck from time to time. I'm not sure if the tooth infection is linked to the discomfort on that side of my face or whether I have a sinus infection. Should I return to my dentist or go to the doctor?
