Is it easy to order more trays after Invisalign Express treatment?

Question

I'm on my last tray and my teeth aren't where I want them to be. I'm hoping I can get like one or two more trays because that would definitely do the trick. I've also heard the retainer that you wear afterwards can do a little movement, is that true? I'm just very worried because I spent all this time and money and so far am not happy. I only have a few days more with this last tray, so I'm sure no more movement will happen. My case was not that difficult either.

Answer 1

No its not, you will have to pay more as the trays are made once only
