Emergency Filling

I've done a bit of digging and found Dental Avenue as a place recommended a slew of times. I couldn't get an appointment until Thursday so I'm trying to see if there might be a better or as good option earlier. Smilelounge came up too, but it feels more "boutique" to me, and this is a filling on my back right bottom molar that a few dentists have flagged as tricky. I've been out of the area for a while so re-learning what's here and best options.
