I have TMJ, I broke the tooth on each side of my 2 front teeth and they got infected. The infection spread to my Maxilla. I had surgery 2 years ago to remove them, the infection cleared, and dental implant posts for crowns. X-rays 6 months ago, everything looked great. In the past week I have had very severe pain in the right implant, pain level is definitely a 10 and I've been having to take Oxycodone. What could be causing this pain?
