I've been considering buccal fat removal and mini neck/face lift for a while now. I also need to get dental work done, as two of my porcelain crowns off my 1st bottom molars (#19 and 30) are now missing. I don't have any pain but the two teeth that were treated with root canals years ago are exposed. Would this be an issue if I want the buccal fat removal first? Or would getting the porcelain crowns replaced be required?
