My wipeout: I heard a chink behind me, and thought I had dropped my keys, so I looked over my shoulder. I lost control, and my face hit the road. Not my head, my chin.
I got three stiches in my chin. I lost two teeth; one was driven through my lip, and I had 13 stiches in that lip (there are three layers in a lip: outer skin, muscle, inner skin). I needed two root-canals. I fractured my mandible, which is now joined to the maxilla on only one side. I was concussed, and wound up sleeping about 15 hours a day for the next 3 months. I couldn't chew for ages.
A motorbike helmet might have helped; but not a bicycle helmet.
