Gums moving after upper front teeth crowning. Is this normal?

I had my 2 upper front teeth crowned 5 days ago. The middle of my gums that goes over the centre of 2 upper front teeth (that looks like a triangle) seems to move up on certain lip movements (particularly when I twist my upper lip inwards). the gums between 2 front teeth flips up, like it is being pulled by the small piece of the tissue that connects the lip and the gums. Is this normal, and will be resolved as gums heal and tighten, or is this something that needs to be checked by a dentist?
