I got off the phone with U of Illinois Vet Dentistry and my own vet. The U of Illinois can't see Bella until June 5 at the earliest--they're booked up until then
. I told the receptionist at my vet's office to let me know if my vet has any pull to get Bella in to the U of I sooner than that, but they were doubtful. If Bella doesn't improve considerably over the next few days, I'm going to see if they can treat Bella's case as an emergency and get her in sooner.
