Yes, there can be a difference with dentists. I went to one who was a sadist when I was a kid, and to this day I have terrible phobias when it comes to anything dentist, and I have a mouth full of expensive problems.
I think I have now bought several
brand new cars for my dentist and periodontist as a result.
I have to go every three months for cleaning, and that's the EASY part.
I will spare you the gory details.
