Try looking in the yellow pages. Sometimes a dentist will meet you at their office for emergencies. Sorry about your toothache. I've had one for a while myself but I'm too chicken to go get it pulled. Just take lots of ibuprofen. Good luck.
Do you have a regular dentist? Mine is closed on Sat, but will come in after hours if needed. (for regular customers) Good luck!! Ouch!
I think Riccobene is open for a half day on Saturdays. So you gotta hit it up in the morning before it's too late.
