I wonder the same thing. I know I will need work in the future. Ask some of the veteran T/H members on the forum or search the occlusion effect. Let us know how it went. Hugs and prayers for a smooth procedure!

Thank you! I don't know if I should be too worried since my T was ear infection induced (or does how we get it even matter?), but I'm still super worried. I really didn't want to get this done now but I'm losing my parent's good insurance at the end of the month (yay turning 26!) so really had no choice 
I did a crown in February, didn't have any problems. My T doesn't react to sounds, but you could wear earplugs if you're really worried. I would at least tell your dentist about it, they will usually understand.
Wear muffs.
