Illnesses of the Mouth

[Patrice]

DS: The open mouths - are they always meant to be a scream?

FB: Most of them, but not all. You know how the mouth changes shape.
I've always been very moved by the movements of the mouth and the
shape of the mouth and the teeth. People say that these have all sorts
of sexual implications, and I was always very obsessed by the actual
appearance of the mouth and teeth, and perhaps I have lost that
obsession now, but it was a very strong thing at one time. I like, you
may say, the glitter and colour that comes from the mouth, and I've
always hoped in a sense to be able to paint the mouth like Monet
painted a sunset.
