Can invisible aligners widen a narrow dental arch? (Photos)

HI, thanks for sending your question. Generally broadening the smile depends on how much room exists from the lower arch as well. Although this can be accomplished with clear aligners you need to see a very experienced Invisalign provider to make sure your particular goals can be met. All the best.

Yes, Invisalign can be used to widen arches. I have done this in many cases I have treated, and it does work nicely.  You would have to be evaluated first for attached gingiva and existing recession to be sure that this can be done without creating or worsening the recession you mentioned that you have.
