Yes, I find the appearance and dress of the hygienist can make the experience better.You must have an evil hygienist.
I have been fortunate to have had good ones.
A couple of times I did have a lady that wasn't my regular hygienist because mine was on maternity leave. she was an older lady and new to the profession and OMG did she take for freaking ever to get the job done.
It felt like she spent five whole minutes on one tooth at a time. and she kept leaning on my hair and then asking me to turn my head. I did not particularly enjoy those times.
