Hello ... I am just about done with my first tray of Invisalign. So far things are going good but I do have a question with how my upper tray was cut by Invisalign. If you look at the attached picture you will see that the back molar on the left side is cut straight across and not round like on the right side. When wearing them it is clear that only half of that back tooth is covered. Does anyone else have the same thing? Was not sure if I should complain to my Orth. about this. I did also check my second tray and it is cut the same way as the first. Thoughts??
