Bottom line: How do identify Invisalign tray numbers without the labelled bags?
enlocke09Jan 16, 2015
Please help! I have both tray 1 and tray 2 of Invisalign, and they both feel exactly the same, when I put them on. I would like to progress to tray 2, but I am not sure which one is which (lost the labelled plastic bags unfortunately).
