@Roberta,
Don't you just love the hoops they make you jump through? You go places prepared for the worst and it's made worse than that.
Costs, don't worry or think of, they'll be in the future.
For the tooth, get a Rubiks cube, snap off one square, split it open, file it down, there! You have a nice cap (there's clearly a reason I'm not a dentist).
Now try to keep your mind otherwise engaged, and remember the lesson you learned today, always go to Bellevue with your own supply of paper (this applies to most hospital restrooms from what I've seen).
