Thanks to your recommendations, I found a dentist for my husband to see yesterday, who thinks he needs a root canal. Now I have a new dilemma. She put him on an antibiotic and Tylenol 3 (which haven't helped yet, he barely slept last night) and referred him to MJ Endodontics. I looked on their website and they are CLOSED today. Ugh. Any suggestions for a dentist who does root canals and is open today so he doesn't have suffer through the weekend?
