how do modern braces work? How can just two strings of wire pull your teeth in some directions, when they actually are held by the teeth?

They’re not strings, they’re spring steel. They get bent into the shape your teeth ‘should’ be, then attached to the braces, putting the wire under tension in whatever direction, pulling your teeth into the shape the wire Wants to be… (this is a really slow process but it’s happening)
That’s why you need to go in every so often to have them ‘adjusted’ with a new wire bent slightly differently (closer to what it should be)
So they do the back teeth first which are harder to move, so in my case I wore the now for a long time to shift my back teeth to the proper position. Then when I got braces the front teeth pulling against the back teeth would set everything right.
It’s a thing called tension. This may not be true but I have heard back in the day if you wanted to fix your teeth you pushed on them with your tongue a lot and that slowly pushed them back into place.
