If we make skin and muscle cells when we heal cuts and heal/generate bones after breaking them, why wouldn’t we be able to grow a finger if one is cut off?

Cells are great at looking at their buddy and saying hey whats your job again? Oh yeah i can do that. Lets do that together.
They arent good at saying what was there before and going back to the manual to figure out how to make that part from scratch. If humans could do this we would likely learned to grow more teeth rather than just 2 sets.
