I Love my invisalign, I have been dying to get my teeth fixed my whole life and as an adult I did not want metal braces. When I first got them put in it was really painful, but as the weeks have come it has become eaisier to bare. i am currently on try 15 of 44, i know this seems like a long time but i have already seen a huge improvement. This was a great investment for me. Advise: you will get used to them in no time. change your trays at night. soak them in order to keep them clean. and always carry oragel!
