I had my braces installed on Aug 15, metal top and bottom. I got violet ligs. For the first couple of weeks, when I looked at my teeth in the mirror I was freaked out by how dark my teeth looked, like I had huge chunks of chocolate smeared all over them !
At my first adjustment on Sep 12 I switched to light blue ligs. It's amazing how they obliterate a lot of the darkness of the bracket even though they really aren't covering up much of it ! I think I will continue to wear this color, or other light colors.
SO for those of you who are newly braced and also going through the shock of seeing dark all over your teeth, try the light colored ligs, I would recommend light blue in particular.
Btw, I can't speak about staining, I'm not an adventurous eater though I have had dark fruits and tomato sauces with no apparent change in lig color.
