I have discolored crown followed by dental implants. Why is my implant color black? (photos)

HelloFrom the photo, I believe the gray / black area is either the head of the implant or the abutment which is showing through the gum tissue. This happens typically in patients with thin gum tissue or if the implant is placed too far out which results in thin / lost bone and subsequently thin / lost gum tissue. The darkness of the crown itself is either due to metal substructure of the abutment. Typically in the smile zone, the following must be considered: Position of implant, how deep it is placed, how wide it is, thickness of gum tissue, choice of material for abutment (ceramic or titanium, titanium masked with white, etc) , choice of material for crown (ceramic, metal / porcelain, gold / porcelain, etc).  I agree with your concern about the color and its aesthetics- particularly in the front of the mouth in the smile zone. This will not fade away and has potential for becoming worse depending on the type of tissue you have.I advise to discuss this with your dentist or seek second opinion from a skilled general dentist or prosthodontist.Dr. Kazemi

It is very important to check the bone height , because this is what determines the amount of gum that is around those implants, x rays are necessary and if you want ho improve the smile ,you will need to think about working porcelain veneers on the other teeth, and changing the crowns over the implants, this way you will have a beautiful smile back. I hope this helps
