Is it optional or do they have to do it? Do they have to put you on laughing gas when they whiten your teeth? When you get your teeth whiten are you not allowed to eat certain foods? Does it hurt when they take your braces off?
-It's optional. -No. -Eh, I wouldn't suggest drinking Coffee right after. xD. -Barley, it's tolerable.
Yes, they do. My friend recently got hers off & they whitened them for her.
