If you don't mind going to Long Beach Dr. Ha is exceptional and kind.
He may be willing to take payments, I don't know, but I do know his work is excellent and he hasn't charged me crazy amounts of money like so many others have here in Los Angeles.
I have had a much better experience with him than with USC dental school. Good luck, I know how horrible that pain is. Also, your GP might be willing to give you a prescription for a couple of pain pills until you can see the dentist. It's worth a try.
(For God's sake, don't go the illegal pain pill route, no matter how much you're hurting. Fentanyl is a real problem in a lot of things these days.)
