Having sung the praises of the RAF Dentist, my most memorable visit was when I travelled over to an appointment with a Wg Cdr at the Swinderby surgery. I had a large molar filling to be done and he just wouldn't have it from me that he had injected anaesthetic into the wrong side of my mouth.
The filling was duly done with me leaping around like a tasered burglar and receiving a lecture about the damage that could be done with a drill bit going at 4000rpm. I'm sure they're better when dealing with braces...
