ts hurts so unbelivably bad, like its to pull my bottem jaw fowards to fix my over bite so not only do i have that but because my retainer is new its tight so that hurts too, its so much pain and i have to keep it for 20-22 hours a day and i have 2-4 hours a day TOTAL to have it off and can only take it off when eating or drinking... GET TS OUT MY MOUTH.
