How about having a root canal without being numbed or sedated?
You're watching the drill being directed toward your face. The dentist keeps hitting the pedal that makes it accelerate. zweeer. . zweeer. . You've heard that sound before and you know what it means, but have you forgotten? It was so long ago...
The drill comes closer and you feel the metal against your upper lip, as the dentist adjusts to get the right angle. Then it lands on the tooth, with a loud ZWEEER, that seems amplified by your empty head (empty... because if you had half a brain, you would have taken better care of your teeth and you would never experience this).
The drill begins to grind into porcelain and you smell the odor of a dead animal (that should be in the worse smell thread). At that moment, you grab the arms of the chair. You want to YELL, but you can't for fear of getting your tongue cut off by the drill. The pain shoots up to your eyeball and through to the back of your hollow head (remember... no brain?).
So... you suffer through the grinding of the drill, as time seems to stand still. You think about how great it will be when you get out of there. The dentist office has become a personal Hell.
Now... the dentist seems satisfied that he's removed the rot from your sick tooth and places the drill on a tray in front of you. You relax, because you made it through the worse part.
Or... was that the worse part? Suddenly the dentist has both hands in your mouth. He starts pushing what feels like a huge rat-tail file into your tooth. You feel it hit your gum and go clear to your eyeball. You want to say something, like: "Watch it! You're gonna poke my eye out!" But, again, you can't say a word, since he's forcing your jaw so wide, it's sure to pop! Up and down he goes, moving the file, to remove what's left of the nerves from your tooth, gums, roof of your mouth, eye and half of your face!
Now... the dentist removes tha file and squirts water in your mouth. He tells you to spit and you're tempted to spit it on him, but you warily look at the drill on the tray and think better of it. The worse is over... Relax... All that's left now is the filling... Then you can go out to the reception desk and confirm your appointment for the next root canal.
