What happens if you change the Invisaligns 2-3 days late?

If you are late on changing your aligners, there is no harm. This will only mean that your treatment is now a couple days delayed, and the day you switch your aligners in the future will be different.

Not a problem at all.  Just extends treatment time.  However, going longer does not make up for not wearing 20-22 hours a day.  

There is no problem if you change the trays 2-3 days late. It is always OK if you wear the trays longer than you are supposed to. Issues may start if you are wearing them less. Just make sure you are wearing the next trays for the prescribed amount of time as well -- this may require adjusting your appointment if necessary.Great question!- Dr. Pam

Dear Sarahill,Thank you for posting your question on Real Self.  I will answer your question the best that I can with the information given.Do not be concerned with changing your aligner a few days later.  The only consequence is that you are 2-3 days behind in your treatment time which is not a problem.  If you are consistently late changing your aligners, I would mention it to your doctor so they have a better idea of your date of completion.I hope that this helps and good luck!Best,Dr. Jenn

The timing isn't as precise as one may think, we don't look at the second hand of a clock to switch at the right moment.  The issues with timing are usually trying to switch too early/soon.  Longer is better, as a rule.The teeth won't move any more than with "perfect" timing, so it isn't beneficial, it just isn't BAD either.As long as you are following the protocol per directions, then you should be fine.The concerns that are most common are when Invisalign aligner trays break or get lost before the next aligner is due.
