Abutment showing through gum line. Any suggestions? (photos)

I do not think that this is anything to worry about.  Your doctor should use a Zirconium abutment that is white and this should block it out.  It should turn out nice in the end.  Best of luck.  

It's difficult to really see anything in the pic. If you have pain, this would not be normal. But if you are ok, go see your surgeon for the big reveal of the implant itself and then you will have another abutment that is surrounded by the gums. Once a temporary crown is placed, you will get a better idea of the appearance and how it will look. But not to worry at this point. 

It is hard to see from the picture, but it appears to look fine. The healing abutment that you are seeing is a thick metal cap that screws into the implant. That part is removed before putting in the permanent crown. The actual beginning of your implant is far below the gums, invisible to the eye. So when the final crown goes on you will not see that metal part anymore.
