Meg would turn white with
fury when people looked at him and clucked, shaking their heads sadly.
"Fury" also has the "property of being wild or turbulent"--this would fit the nature of a high school teenager who's unhappy with the way she looks, upset that she is in danger of being left back in school, tearful because her father is missing, and willing to let her anger take on an older and heavier boy in a fight that results in her having a torn blouse and big bruise under one eye.

Meg bared her teeth to reveal the two
ferocious lines of braces.
"Ferocious" is not an adjective often used to describe braces, especially since braces are meant to straighten teeth instead of sharpening them to make them dangerous. The ferocity of the braces comes less from the barbed lines of wires and more from the way Meg is deliberately using them to reveal her anger at the principal's questioning of her father's occupation and whereabouts.
