‘They took it down. It was terrorising the patients'
I'm not afraid of dentists, but I did go to one for several years who was probably a sadist. He seemed to relax when I was put through pain. I know that some people have tooth dreams. Everything that's part of the vocabulary of the unconscious has some depth to it – people are interested.
As part of the Manifesta exhibition in Zurich last year, each artist was paired up with someone in a profession, and that person would then become our host while we were in the city. At first I was looking at working with a personal trainer, or someone who works with animals; I'm interested in how people handle animals. Then I realised I'd already done those things.
