I just started Invisalign today and noticed the gap between the top of the trays and my gums it doesn't cover my whole tooth. Also I have space at the Invisalign edges of the trays. The fit is really snug and the attachments seem to be in the correct place I can't push them up any further. The template was this way as well. I guess I was expecting this to be a little less noticeable. Should I be concerned?
