Jack will be just fine, and good for you for being so observant and noticing. Yes, brushing his teeth weekly is better than most of us do. I give mine "Greenie Treats", and so far, so good. Oliver had to have a General Anesthetic at the height of his illness, and he did just fine. I'm sure Jack will also.
Since today is Tuesday, I think you meant to say he would have his tooth extracted on Wednesday (tomorrow), or perhaps I am misunderstanding. Gosh angel, you are stressing. Please don't worry. He is in excellent hands, and will be just fine. This is not Emergency Surgery insofar as they are unaware of his condition and medication.
I hope both of you feel better soon. Do keep us posted, on BOTH of you, please. ♥
