I am on my second tray with invisalign and am so very happy I made the decision to do so.When I was younger I had metal braces and when I finished with those, was given a retainer to help my overbite. However, being the teenager I was, I did not wear my retainer therefore was left with an overbite.As I grew older, I began to take more notice of my smile. All pictures that were taken of me I always hid my smile.Just after two weeks of invisalign and many people have already commented on how much of a difference. My confidence has different been boosted. Highly recommend it!
