I just finished my first trays. I put on my second tray and then got curious about what the next two sets (3&4) looked like. Each package is marked U & L 3 & 4 but the trays inside are both marked U & L 2. I even tried on what should have been the 4th set and the feel just like the ones I'm currently wearing. This must be a mistake right? I am going out of town and want to be sure I have the correct trays with me.
Should There Be Multiple Trays with Same Number on Them?

Trays with same number
Each successive tray should have a different number. If they are not different I would speak to your dentists and find out what is going on. I have done a ton of cases and never have seen that
Multiple Invisalign Trays With Same Number
Each successive Invisalign Aligner should have a progressively increasing number on it. Discuss this with your dentist!
