I am going to have double jaw surgery in two weeks to fix my bad malocclusion (Class II). I started to get very nervous about the surgery since it is getting very close and real

So one of my molar and canine is problematic and I am very worried about how they will take the surgery and elastics.
My molar has a crown on it and it has been sore and slightly sensitive to cold for the last 2.5 years! I have seen at least 4 dentists about it and they say it looks good. They thinks its problematic more likely because of my bad malocclusion. I was told my crown can be changed if it wont get better with a good occlusion after the surgery.
My canine started to be sore and sensitive after 6 months of wearing braces. It freaked me out crazy that it is sensitive to warm drinks. I drink my hot coffee with a straw and make my meal gets cold to eat

Has anyone had any tooth issues before surgery? I am worried if I need anything to be done to those teeth after my surgery while I cannot even open my mouth and recovering from the surgery itself.
Sorry if I sounded annoying. I just needed to vent it somewhere and ask the forum about it.
Thank you...
