Thanks for the report! It sounds like it went pretty well, so good for you!
You probably have to let the dentist's office know tomorrow, huh? I don't know - I would call them and explain the situation, and see if they can't move your appointment a little bit, so that it still suits your time frame.
But that's just my opinion, and I haven't had LIS done. But I have had wisdom teeth out, and depending on how they are (impacted or not), it can be anything from smooth sailing to a bit painful.
Good luck in your butt healing process!!
PS - if you let the dentists office know today, maybe there's a larger chance you can swap times with someone who is scheduled for later next week...
