Was it smart to skip a tray? Will the teeth adjust to the new tray or should I call my dentist and have him order me a new one?

I would recommend calling your dentist to request a replacement of the tray that you stepped on.  It's really not a good idea to skip a whole week of the previous tray because it could cause you to have be in refinements for several months following your scheduled Invisalign treatment.  Invisalign is very precise and accurate when used properly, but can really have horribly slow results when used incorrectly.  Good luck to you and I hope this helps.

In my practice, I tell my patients to skip an aligner if they lose or break current ones, however if the new aligners don't fit properly after couple days in them  I would ask them to contact me to evaluate.  After evaluating, I can decide if I want to order a replacement for the damaged ones or if the next set fits properlyI would contact  your orthodontist to have them look at the fit of the new setGood luck

Skipping an aligner tray is generally not a problem if a week or more of use has occurred. Each Invisalign  aligner tray is designed to sequentially move teeth according to a preset Clincheck plan. While most of the teeth movement occurs during the first few days of aligner use, the recommended 14 day (two week) use of each aligner is to allow the important supportive dynamic process of bone resorption and deposition around the teeth to occur. This process, if cut short and movement of the teeth occurs too fast, can damage teeth with root resorption and weaken surrounding bone.With that said, an exception of changing aligner trays after one week of use due to damage/loss should not be a problem if the subsequent tray seats properly and fits correctly. However, if aligner fit is a problem, I recommend wearing your previous aligner and a replacement aligner for the damaged one be ordered prior to wearing the next aligner.
