I've had my front teeth knocked out. Twice.
But yeah - never did they shatter. OUCHIE.
Stupid related story: In my mid-20's, I had to get said teeth replaced, since they were coming loose.
(literally my two front teeth)
To do so, the dentist had to grind down the 2 adjacent teeth to pegs, so that the 4-tooth bridge would have a place to be attached to.
I had removable caps for that, while the bridge was being fabricated. So...
For Halloween that year, I went as a hockey player.
Rangers jersey, gloves, helmet - and 4 missing front teeth.
Everybody was like "damn! That's soooo realistic! How did you do that?"
