Invisalign is a series of clear aligners that you switch out every two weeks. Each aligner gradually shifts your teeth into the proper position. Invisalign is started by taking an impression and photos of your teeth and then designing your final smile on the computer.

We also know the number of aligners it will take to complete your smile transformation, with each aligner being two weeks, we roughly know how long your treatment will take.
