You mentioned mouth pain in connection with former root cannals. do post to Bryanna, on Private messaging if you want. She may be able to help with any questions you have regarding your mouth, and possible problems left over from the root cannaled areas. gosh I wish you could get a diagnostic on that. Why is your insurance company giving you a hard time over the testing?. That is the only way to get the diagnosis. I do not understand insurance companies. appeal their decision with a doctors letter, that sometimes works. Have a good night. ginnie
