So I am on Invisalign, and I just started my 6th Tray out of 26. I have been on a 2 week system, as normal. My orthodontist said my teeth are moving nicely and I can change my tray every 1 week. Nobody online seems to be on a 1 week system. Everywhere says 2 week, so I am unsure if I should change. What do you think?
