Q. Hello. I am 23. I got braces on back in December 2007, and I got my lower ones off in January 2009 and my upper ones off sometime in february 2009. I have a permanent retainer on my front bottom six teeth, as well as one on my upper four front teeth. I was given a retainer to wear nightly on the top and bottom. During the summer I kind of forgot, but now I wear it all the time when I go to bed. I went to the dentist about 3 weeks ago. Ever since then I feel like my front four teeth are moving. They dont look like, but they move slighty. If you know what I mean. But it looks to me like my tooth beside my front tooth is moving away, about to leave a gap. Maybe I am paranoid. But people have told me that it cant happen with a permanent retainer. I need your help!!
