The lower teeth are moving
I think, this month the lower teeth have moved a lot. It should be visible when comparing the pictures to May 9. There are now a couple of gaps near the gumline because the teeth are kind of tilted right now.
This morning, I noticed that the lower teeth may touch the upper gums a little when biting down all the way. Also, one tooth was aching a bit when I woke up.
My lower teeth are not really in front of the upper, I just tend to move the lower jaw like that for pictures.
