Can Invisalign Cases Be Too Old to Transfer?

Find out if you're case is still "active" and if it is then you can do a mid-course correction or refinement case which doesnt require completly starting over..Remember tho the new dentist also needs to be paid for his work and its a difficult situation to get money form your old dentist to give to your new one to continue work on your case..

Invisalign does indeed have an expiration date.  It usually 3 years after the treatment is started.  Once that date is reached you can no longer do refinements on the case.  I would contact your original dentist to see when the case was started so you can see if it can be transferred.

Invisalign does have a time constraint on their prescriptions.  In other words, you have to work through the original treys as prescribed or they will not issue any more after a certain period of time.  If this time limit has expired in your case, then new impressions (hence a new lab fee) would have to be assessed in order to proceed.
