Hi Chicklet,
I just had arthrocentesis today!
I have experienced much of the same after-effects as you, though I imagine by now you've got it all worked out. My bite was opened quite a bit too, but only for a few hours. Now it's back to normal.
I'm worried I'll have to get the procedure done again. It was.. painful. Or just really, really strange feeling and sounding. Did you hear / feel crackling and stuff as well?
Regarding the teeth touching thing, my dentist said that it would feel like my right side won't meet up (the affected side) but that that would go away soon.
Here's to possible relief!
