Invisalign was awesome! I wore braces as a kid and after 40 years my bottom teeth had really moved (almost criscrossed) and my upper teeth had moved out and one front tooth had moved as well..
Here it is 13 months later and my smile is really beautiful..
Don't hesitate for a moment - but you MUST be diligent and wear the braces!!! If you don't, you're just wasting your time and money.
