ELI5: After a tooth is removed how is it that the hole left gets completely filled over time?

I understand how the wound would heal but how does the body know to fill in the entire hole left by the tooth removal? That space didn’t have any gums before, since a tooth was there but it all gets filled.

Dentist here - inflammation and normal trauma processes carry out cell growth, tissue differentiation, repair, etc. like they would for any wound. The body doesn’t like voids and will fill them. They first heal to close the wound, then slowly over time remodel into a smoother shape (bone and soft tissue).
