Was Spencer OK after the tooth was removed?

I am taking back to the vet tomorrow. They are going to put him under to do the full dental and mouth exam. Thanks for the input.

My Basenji Egyn (my son named him that because he said he looked like the dogs from Egypt) is very sick. He has trouble eating. When he starts to eat he yelps and will not let you go near his mouth. I took him to the vet and the vet said his mouth and tongue looked red and irritated. He gave me antibiotics that he has been on for 10 days. He does not seem to be improving. I can tell he is in pain. I am taking him back to the vet on Monday. Has anyone heard of these symptoms?
