How does Invisalign work?
It's easy to understand how braces can straighten my teeth, but I don't seem to get how something as simple as Invisalign can do the same thing. Does it push the teeth forward? How does it apply force to move the teeth? Both of my canines are protruding -- they pushed forward because of the crowding, and now I want them fixed. Is Invisalign a good option for me?
