Jennifer, I am sorry you are going through that and have been for a long time. I have found your information very helpful. I am going to contact a medical clinic in Searcy, AR. They are associated with the Mayo Clinic and have access to their doctors. I will definitely keep this in mind. I can just as easily go to Dallas. Dallas is actually closer for me. I have already been to a periodontist in Longview, TX. My dentist sent me to him.... He told me a lot of stuff I didn't know but dismissed me when he found out I had been diagnosed with Sjogren's Syndrome 20+ years ago with no symptoms yet. He blamed it on the disease. I know this is a symptom, but my test results have actually gotten better not worse over the years. I have been monitored every 6 months. He just went to Sjogren's and was done. That was his answer. I need someone who has seen this before. The former dentist that responded to me said that the crown was too tight and didn't fit. She deleted her response to me. My dentist said everything is exactly the same as the crown he took out.... He certainly had a tough time getting this one in there. It took two tries., and it seemed he worked on me forever! He also ground part of it off the top and edges. I have wondered if I got the correct crown or if something I am allergic to is coming out of that crown that is now rough on top.
