There isn't much braces, maybe a bit less in terms of quality than the first one, but there is still some.
In the beginning where it goes through the introductions of the 3 girls who grew up to become the Charlies Angels, it shows Cameron Diaz inside a mascot costume and she trips and falls and loses the costumes head, showing Cameron Diaz rolling around on the ground laughing in her braces and cervical headgear.
Later on in the movie Cameron Diaz is at her boyfriends high school reunion and it shows a cardboard cutout of him in a mascot costume without the head and wearing braces and cervical headgear (just like Cameron Diaz at the beginning of the movie). It's supposed to be funny because they are both had braces and headgear in the past and they were both dressed as mascots (to hide their braces?).
It's nice to see some braces and headgear in this movie, but it's nothing monumental.
A movie like 'A very Brady Sequel' with Jennfier Elise Cox in full braces and high-pull headgear is much better. She's on screen for a longer time, with some good close-ups, now that's something to get excited over!
