The first three extractions went well. But on the fourth and final one the tooth fell out of the clamp and into the back of my throat. Thankfully my tongue automatically pressed it against the roof of my mouth so I didn't inhale it.
The dentist made panicked sounds but the assistant had the sense to grab me and set me upright as I gagged on the tooth. I coughed it out and heard it ricochet off the wall and across the tile floor. @andrew
