Dentists in the city

Hey everyone. I've spent the weekend in bed with the worst toothache I've ever experienced and will probably have to see a dentist next week. My problem is that I don't get paid until Friday and simply can't afford the procedure I'll most likely need (root canal) before that.

I've tried looking around for dentists that offer payment through invoice, which usually buys you a few days, but I've been unsuccessful so far. Anyone know of any dentists that offers either payment a few days later or through an invoice?
