What Happens if You Dont Wear Your Invisalign for About 2 Weeks?

There will be a day or two when the teeth hurt, maybe even badly.  It is not uncommon to need to revert back a tray to get teeth moving again, then progress as before.  It just means that you are about a month behind treatment, but it should not pose too much of an issue.

Your teeth have probably started to move back to the old way they were. You did the right thing by putting your last tray back in, I would wear that for at least a week and then try again.  If it continues to be uncomfortable I would contact your dentist. 

Remember that not wearing your aligner trays for two weeks or more during active therapy will almost always result in a degree of relapse. So, to get back on track after "driving in reverse" do the following:


Use the previous aligner tray prior to the "active" aligner tray that was interrupted.

Change to the current aligner after a "reboot period" of about two weeks.

Change aligner trays at night before bed which will make it easier to get in and out in the morning.


The bone around your teeth during any orthodontic movement is in a dynamic state of deposition (making new bone) and resorption (taking away old bone) and it is important for this process to not be interrupted by inconsistent or improper use of your aligner trays.

I would recommend returning to your orthodontist/dentist to see what is going on with your trays and tooth movement.  More often then not, you can go back one aligner, wear that for 2 weeks, and return back on course.  Id put in the aligner that fits to stabilize your teeth and make an appointment with your doctor as soon as possible.

Sounds like you did the correct thing. Go back to the older tray and wear that for at least 1 week, and then continue with your regular schedule. To avoid confusion, go back on both the upper and lower trays.
