My top teeth don't move that much at all. If I don't wear my retainer for a week, the top still pops in just fine. But that bottom one does not want to go on. Yes, I admit it : I don't wear my retainer as often as I am supposed to.

I am hoping that between my dentist and the orthodontist that something can be done this year with the bottom teeth. If nothing else, than maybe a small daytime/night time metal retainer to go over those bottom teeth that is removable. Anything to get rid of that huge clunky Essix retainer.
