I would like to know this too. My dentist wants to put me under due to problems with head movement. I've been putting off needed dental work because of this. Thanks.

I would be intereted to hear any other "dental" stories horror or otherwise, so I can pass them on to our new advisor. Thanks Joy Graham >>
