Okay so I am not so smart.
I just got my retainer about a month ago. For some unknown reason even to myself I put them in very hot water to clean them. I did not think they would melt so easily. I called my Orthodontic office and told them what I did and that the retainer now does not fit right. They said I can have a new one but it would take at least three weeks for it to come in. She stated my teeth may shift a little. Is there anyway i can fix my old retainer until the new one comes in? I want to keep my teeth from shifting.
