i got my impression for my retainer 6 months ago. Betwween 6 months ago and now there was so shifting of my teeth. Finally my ortho said i was fine and i could get my top braces off. I got my top braces off and i got my retainer. Now when i put my retainer in it hurts really bad. I have two questions
1, What should i do?

2. Do you think as a result of my teeth shifting in between i got my braces off and the impression, that's why it hurts so much?
