Will my gum settle down around my new eMax crowns? (Photos)

I can see you dentist did a good job with the crown contours. However, the gum between the teeth may or may not grow down to close those spaces. There are some solutions to the problem, including injection of fillers to close those dark triangles. 

Thanks for posting the photos. There are many things that cause a black triangle at the gum line. The height of the bone and the contour of the crowns are two of the major ones. I would give it a few more weeks, but if you are dissatisfied with the results you should contact the dentist. They will want you to be happy with your outcome.
