I’ve already had a midcourse correction. Moved into tray #7 of midcourse correction and noticed lack of tracking. Moved back into tray 6 for 2 more days, but tray got very loose and uncomfortable. Teeth were no longer “wiggly” so went back into #7 today. Incisor is behind the upper canine, so I know it is a difficult movement to achieve. Dentist is against extractions and (dentist does Invisalign. I don’t have an ortho) already did one midcourse correction. Using chewies and getting discouraged.
