Hello. I have just started my Invisalign treatment and yesterday have received my week 1 tray. While try to put it on i have moticed that my bite is weird. I cannot fully make my top and bottom teeth meet. My mouth closes but my teeth dont meet there is a gap. Also i feel that my left posterior teeth and the aligners have a slight gap between them which could cause the whole problem. I tried removing and re-inserting the aligners but no success.
