My goodness when I think about teeth and dental clinics I feel sick, that's just how much phobia I have for dental health. Anyway, I have had my teeth done a couple of times, I started having teeth problems when I was very young and I still have the same problem even now. I have never overcome that fear of drills and needles, that's on a lighter note. After tooth crowning, it takes close to one week to heal. That only happens when you visit a good doctor who knows what they are doing., if not you could even end up with an infection because of recklessness. Crowning is very uncomfortable especially if its your first time having it done. When you bite on something you tend to have that fear of the crown coming off, so you have to keep reminding yourself that it is permanent to be comfortable.
