Are you scared of the dentist? I got used to it a lot as a kid.
I am actually scared of them a bit.  My early experiences with them were not pleasant.
Oh I am sorry. Did you have a bad experience with the dentist themselves or their aid?
The dentist themselves.  It was in another country though (Russia) and quite a few years back. 
Oh that is crazy. Be thankful it wasn't China or France, the first people there to practice dentistry were barbers.
Oh wow really? Thats so interesting.  Do you know anything more about these barbers?
Well they were originally called the "Guild of Barbers"
Thats a cool name.  How long ago was this?
this was around 1400, since it was banned in France from having them practice.
