Mostly due to being hurt badly when I was young by a very unsympathetic and mean dentist. I was never the same after that.
Me too, when i was a teenager. A dentist drilled on a tooth, and i wasn't as numb anymore, and i felt every bit
of that pain. And he had the ****s to yell
at me for jumping out of the chair (oh, yes, he was right, i should have just LAID THERE!!!!!). His entire "chairside" manner left a lot to be desired, not to mention his total disregard for his pts.' time. I could understand when cases run later, and you're waiting for awhile in the afternoon, but the last appt. i'd had with that idiot was scheduled at 8 am sharp, and he rolled into the office at 9:05.
Thanks to that experience, i have to have something to relax and sedate me before i would go into a dentist's office. It's pretty bad when one DDS ruins you for everyone else.
