I keep mine closed in the vain hope of keeping the tears in.

But, being British, I hardly ever go to the dentists anyway. :gums:

My dentist has a television set mounted on the wall and always asks me what I want to watch.

I always worry that I'll look dead or something if I'm laying there with my eyes open. I make a point to close 'em, but sometimes I can't help but open 'em and try to see what he's doing. One of the more important things, I think, when someone is shoving their hands in your mouth, taking note of every imperfection, is to retain some sort of decency in your appearance at least...

I always keep an eye on the pretty dental nurse.
