Duration of Invisalign Treatment for Teeth Gap?

Invisalign might work. It depends on how much movement in total. Usually 0.2 mm of movement every two weeks is the amount of movement you should expect. However, sometimes the teeth need to be moved out of the way and then back, so it isn't always as simple math problem of adding up spaces. Visit an Invisalign provider that has treated a case like yours to see what they predict.
