I am struggling with this very issue right now for Sally. How bad are her cavities? Sally has quite a bit of teeth missing already (they were pulled at the shelter she was dumped in, or even possiby during her over breeding years) but there's one tooth that has gotton infected now twice. She finished a round of antibiotics and she's good now but I was told that if the it gets infected again and I don't get it pulled it could "kill her." I'm at a loss of what to do, as you, I too am very concerned that she would not pull through a surgery. She's anywhere from 9.5-11 (we're really not sure of her age). Right now I'm sitting tight with her keeping my fingers crossed, but I doubt I will have it pulled.
Oh, Jeannie, this sucks! Will keep prayers going over Sally's
teeth staying healthy & no surgery needed, BIG hugs for you!
