Thank you, Bryanna; from reading the posts, I knew you weren't a dentist, but sometimes nurses know as much or more than doctors, too.
I was also worried about the infection spreading further from tooth #3. I asked the endo about this and he said that upper canine tooth infections could spread to the brain, but not back molars. I hope that's at least true!
However, I don't want to wait months to see if a retreat helps with the infection, and from what you've said, it won't help at all.
I am going to call an oral surgeon on Monday and make an appointment for a consultation. I want these teeth removed yesterday!
I will keep you posted and appreciate your time!
