ELI5: When teeth are moved forward with braces, how do they stay in the skull?

r/

My teeth are at the edge of my jaw. There is teeth, a small amount of gums, and then that’s it. When I look at pictures of human skulls, you can literally see the teeth root.

Invisalign does not change the size or shape of the jaw.

So when bottom teeth are pulled forward with Invisalign, how is that possible? How can teeth at the edge of the skull be moved forward, and the skull/jaw isn’t moved, and the teeth stay in place? How can I be sure my teeth won’t just fall out?

    Had them for 4+ years. They move your teeth slowly and when they move, the bone of your jaw fills in the empty space (bone remodeling). It’s an incredibly small movement, which is why it takes years. There’s never a risk of your teeth falling out of some hole that’s been created (unless you have a condition that impacts bone growth or something, but then they probably wouldn’t give you braces in the first place)

    Simply put, teeth move real slow over multiple years and the bone heals into the empty space.
