I have been having left upper teeth pain for three months or more. I had a root canal but pain didn t go away. So I had it pulled. Imstill have pain and can see root exposure and a tiny hole beside upper left canine that I think exposes a nerve because I get shooting pain there. My dentist doesn t see anything in X-rays. I m on medicine but it doesn t help the pain.
Hello and thank you for your question. I think you should go into another dentist for a second opinion about your symptoms.  It sounds like another tooth is in need of a root canal or restorative therapy due to the pain not being alleviated by the extraction of your tooth.  Not all cavities are seen on radiographs and can be found intraorally upon inspection.  Please find someone in your area and have it looked at.  You may also have sensitivity due to root exposure and should use Sensory to see if it removes the pain. Best wishes
