LOL, mystery solved, but I am going to have surgery to repair my gums so I do not lose my teeth. The grey gum thing was a reaction to some desensitizer the dentist put on my teeth. The Periodontist did say that my gums are receding due to the rads. He said that if I wanted to save those teeth i would need some surgery done on them. Finally got to someone that knew what he was talking about. I got back in 4 weeks and we will schedule surgery then. I have already talked to my RO, and waiting to hear back about what I do for surgeries.
