very nice - you like imagery - gritty, ugly and violent at times - reminds me of Atwood. You redeem the mundane with imagery...she’d held the words tight between her back molars—resisted talking, resisted trying...pushed her tongue against the top of her mouth until the pressure in her head forced her to stop.

Can't say as I've ever felt that so it pushes credibility for me, but it might be your style, so in that case you have to go with it.

As I said, nice :)
