Tom Cruz has two movies with braces in them.  In Coctail, about the middle of the movie where he begins to bartend, people are shouting drinks out at him.  There's a girl with clear braces that shouts for a drink.  It's brief but it's a good closeup of her mouth.  Aslo in Jerry Mcguire, Renee's character has all her gf's over and they're sitting on the couch talking.  One of the girls there has braces.  There are several shots of her.
