I sat in a dentists chair in South America with my mouth held open for an entire working day once before, with a 1 hour break so the dentist could have lunch. Aside from that, I had another bad experience with a horrible dentist who refused to give me enough anesthesia. What a delightful man he was.... I hated going to the dentist before those experiences, so you can imagine how bad it is now - the sound of the tools, the burning smells, and the sensations against my teeth... makes me physically cringe thinking about it. When I'm in the chair I just completely tense us - it might as well be a bed of nails for all I care; actually, that might even help keep my mind off it :)
