I think I will write a review about the cons of Invisalign, since everyone seems to praise how great it is. First, I started one year ago, and my teeth already look much better . But, unlike metal braces, there is a lot of care in keeping the aligners clean, scheduling your meals and overall diligence. I am now on #25 of #33 aligners, so I am 75% done. But my Ortho put buttons on two of my top front teeth, which are def. evident, especially with the aligners in. I can tell that when I talk with someone they are looking down at my teeth to figure out what it is, whereas with metal you know exactly what you are looking at. I can see the end of the tunnel, but I must say this feels like a sentence more than a treatment.
