The question of the day is “Can Invisalign Expand the Dental Arch?”

The answer is Yes and No. Invisalign does not have a large amount of potential to expand the Dental arch, only by 1 or 2 millimeters, however it really depends on the amount of constriction. In cases where a large amount of expansion is necessary it would require surgery.
