I wore braces before. Pluck out four teeth before putting on the
braces so that I have space in my mouth to push the teeth in....
dunno why must do that, I wasn't even bah gay, only front teeth not
nice.
Before I put on braces, I used to have Juliet Roberts' kind of
mouth, big big smile one.
After the braces were removed, my mouth actually looked a lot
smaller. When I was doing some photo shoot, the few makeup artists
said that I have small mouth. 
Now when I tell people that I had big mouth last time, they all
cannot believe me nor imagine how I looked.
