Invisalign: Tray 9 (lower)

Today, I swapped out the bottom tray only. While it’s exciting to have finished the tray progression on the top, I’m dreading the thought of wearing this tray for six more weeks, until I see the orthodontist again. Despite brushing, the trays yellow after a couple of weeks and no amount of scubbing really gets them clean. I grimace a little each time I put the “old” tray back on my upper teeth.
