I'm the odd one out here as I don't mind the dentist at all. I go twice a year for cleanings/checkups and I lay back with my eyes closed, half asleep. Even if it's more major (i.e. painful) work, I just lay back and try to trance out, kind of like Lil described, but not quite that focused.

OF is right on the money... it's worse not to go.

Hope it goes ok for you, Sharni!
