Hi, so I've had braces for nearly 5 months now,

and I just got power chains at my appointment.

It is wrapped around ALL my teeth for bottom and top, except the teeth at the VERY back,
so I was wondering, which direction are my teeth being pulled towards?

And how do power chains work, because I was searching it up, and it is to pull together big gaps, my teeth were never really messed up to begin with, so there really aren't any big gaps between them. so yeah
