Thanks! Congrats on getting yours off too!
I have a lower bonded retainer so that is saving me from having to wear a lower retainer, I guess I am thankful for that.
My ortho didn't really say anything about things begin sensitive or gums being shocked, wish he would have. My gums were bleeding when I first placed the upper retainer in at the office, that kind of shocked me and they said it was normal. Makes sense though, my gums are hurting and my teeth are extremely sensitive to cold and they are achey too. I also have been having headaches, are you getting that too? Hope this doesn't last too long!
I plan on wearing the retainer all night while I sleep and then I have been breaking the other time (8 hours or so) up during the day whenever I'm not eating or drinking something. I have been trying to keep track of how many hours it is during the day, but I don't know how long I will last on that, you know?
