Call your dentist a few minutes before they open and tell them you have an emergency and HAVE to be seen today. They will accomodate you.

If you have any codeine or the like, take a couple but try to AVOID aspirin as that's going to thin your blood and and increase your clotting time.

Don't do it yourself, if you crack the tooth while trying to extract it, it will complicate things.

If you go to the ER, NEVER request a pain med by name/dose etc. They will think you're a drug seeker and at best give you a shot of Torodol which is only a high strength NSAID.

Good luck.
