I was probably four when I fell against the sandbox in the playground and knocked one of my top front teeth right out. I carried it inside to the teacher, who had me bite on a paper towel to stop the bleeding and sent me home with the tooth wrapped in another paper towel in my pocket.
About a week later I fell against a large wooden block in the classroom and knocked the other top front tooth clean out.
I went for something over a year without top front teeth, but my adult teeth came in early, so it wasn't 2 or 3 years like it might have been.
This was a long time ago, and I still have both the adult teeth, although one of them died when I got hit in the face with a football in the third grade.
All to say that n=1 but it likely wouldn't have been the worst thing if the two teeth had come out.
It was worse than that -- the football thing happened when I had old-school braces, and my lips were literally smashed onto the railroad tracks, so much so that I had to walk to the drinking fountain and pry/peel my lips off the braces, with an accompanying rush of blood. Good times!
I'm a grown-ass adult now, and I haven't had issues like this since my late teens.
