I messed up with my Invisalign and wore set 3 for four weeks instead of two. What should I do?

Don't even spend a nanosecond worrying. It is never a problem to wear an aligner too long. Wearing the aligners our of order or not long enough is something you might need to worry about but your "mistake" is no problem at all. You will need to call your doctor's office and let them know that you need to push your next appointment back two weeks because you will still need to wear your next aligner the prescribed two weeks but the only thing you have done is delay your treatment by two weeks.Good luck!

Thank you for posting your question.  Wearing an Invisalign aligner too long should not cause any problems.  Move on to the next aligner and let your dentist know.  Try to keep changing the aligners on time so that you can finish sooner rather then later.  Hope this helps.  Good Luck!

Hi,
This happens very often with Invisalign, please let your dentist evaluate the fit of the tray you just wore. If the tray you are wearing fits good you might be able to continue to your next set. If the tray does not fit good you may have to go back to your previous sets.
