My dentist asked me that a long while back. My Dr. at the time was certain I had lupus and kept checking for it. She ignored the Sjogren's suggestion completely. (I had to fire her and get a new Dr. as she just was stuck in her certainty that I had lupus.) Only one of the many blood tests she did indicated it "could be a possiblity." I thought that was a little nutty. Either you have it or you don't. Happy to say my next Dr. was the best, but he passed in 2010 due to complications of diabetes.
How do they test for Sjogren's? I've only encountered it one time.
I Thank-You all again, you have given me great information and I am so glad to be able to talk with others who have this...too bad that we aren't just dreadfully healthy and planning a lunch date instead!
