Movement from Night Wearing of Retainer After Invisalign
I have recently finished my Invisalign and I am at the stage of wearing a retainer only at night. I have noticed a significant amount of movement with my teeth during the day. My retainer still fits, but is tight. It's similar to what it's like when I switched between Invisalign trays. Is that normal? Will that settle over time? How much movement should there be while my retainer is out over a 12 hour period?
