I recently had a consultation at the dentist- one I have used for years for dental treatment, but not the same dentist who does facial aesthetics.
I was surprised that during the consultation, there was a dental nurse/ asst in the room. I felt slightly uncomfortable as I expected it to be 1:1.
I've been going to another very up-market cosmetic clinic previously for some time (where the practitioner was also a former dental surgeon and a qualified doctor too) and that was very much 1:1. It became very expensive which is why I've looked elsewhere.
I don't know if the asst was there as she was already in the room, or if she'd be there when treatment was being done.
It felt less intimate and and to be honest I didn't really want her listening to the conversation!
