was nine once
I broke both my front teeth when I was nine (bike, downhill, wobble, panic…).
One tooth had about 1/3 missing, the other was split up to somewhere under the gum. The latter got a root canal, and both got temporary caps since my jaw was still growing. All that took 4-5 visits to the man with the 2-inch needle with loops on the handle for extra grip to make sure I felt it all the way up in my nose.
Funnily, I really did wonder if I could replace them myself with chewing gum.
At age 16 a different guy filed both teeth down to stumps, and put permanent caps on them, with much less pain. It's been 39 years and they're still doing fine.
If they pulled your teeth, then you need either implants or a bridge (false teeth anchored to nearby teeth), and you will get them eventually. If you still have some bone left, crowns might work.
