I had braces when I was a kid, and surprise surprise, 15 years and about $4K later one of my front teeth is starting to think for itself... Anyone tried Invisalign? It's like an 'invisible' mouthguard that you wear 24/7. I haven't talked to an orthodontist yet, so I have no idea what the cost or effectiveness of these things are. Anyone tried it? Any idea of the cost?
