So, she came home this morning. It went as well as could be expected according to the surgeon, and I spent all day with her yesterday while she was recovering. Nonetheless, despite lots of cool packs on her cheek (which were available from a freezer on the ward, cos it was a maxilofacial surgery ward), the side where she had two teeth removed has swelled up hugely and is still very painful. She's taking up to the max allowable limit in drugs (alternating ibuprofen and novalgin, an anti-inflammatory that's not used in the UK, it seems) but is still fairly uncomfortable.
We have the three teeth in a container and I'm amazed how small they are - no bigger than normal back teeth really. The surgeon said that it's because at 16 the roots haven't really developed as much as for an adult.
The ward offered one savoury and one sweet soup for breakfast, lunch and tea 
, for all the facial surgery patients. No wonder the doctor told us to take our own mushy stuff in as well! I was surprised that the doctor said she has to eat mush for the next 10 DAYS! - until the stitches come out next Friday. That's much longer than we thought, and longer than the rest of you, it seems. I'm going to have to get creative with the soups.
"Was back to normal the next day and able to eat normal food. Wasn't too bad"
"I ate soft food for 2 days and was back at work within 48 hours. I was very tired but not in pain or even that swollen."
Blimey, you must just be super-women! DD1 has realised now that she won't be going anywhere for the next week, so is taking the opportunity to watch Game of Thrones on DVD back-to-back as a distraction technique.
When she has the big op next year she'll be off solids for 6 to 8 weeks 
. It involves breaking both her jaws and then resetting them. So this is just a practice run.
One really disturbing note: she was in a bed next to a really nice woman in her 30s who had a broken lower jaw and had to have it operated. Her husband had punched her 
. Luckily she has her sister nearby, who's looking after her small child for the moment, and she is definitely going to leave him now and find a flat of her own. She recognised that there would be a next time if she stayed. Sadly, she hasn't called the police after the incident because she slapped him during the argument so she thinks they'll try to blame her too. I only found out about all this once we were home - DD1 told me they'd been talking at night because they couldn't sleep. Otherwise I'd have offered some help - but she does have solid family support. It's just worrying that he'll try to find her if she doesn't get a banning order.
Thanks for all the advice, twas good to know in advance what others have been through.
