I had a dental implant 2 days ago & the gums around it are black/partially white. Is this normal bruising/gum reaction? (photo)

It is nornal for the tissue ( gum) to get swollen. Blood clot on the site and bruising of the tissue will cause the tissue to look purple- black. It is normal for the top layer of the tissue to slough off and appear white If you have any questions/ concerns regarding your healing, it is better to have the site evaluated by your surgeon Meanwhile, follow the post operative instructions. And try to avoid pulling on the site trying to lift the lip for a picture Doing so, will loosen stitches closing up the surgical incisions therefore , increasing risk of post surgical infection.

Your healing site
looks very normal. As with any surgical or injury location, blood clot
formation or bruising can cause the tissues to appear different until full
healing has taken place. Within about 2 weeks your gum tissue should return to
a healthy pink color.

it is part of the healing process it will go away in a couple of days, don't forget to take your antibiotic and your pain pill.

Its difficult to fully evaluate from your picture. The site appears to be healing for only 2 days out. The white/yellow area may be caused from too much pressure if you are wearing a temporary flipper over the area. If this is the case it may need to be adjusted, and you should keep it out until you see your dentist. The black area may just be your blood clot or if a laser was used during the surgery it can often make the gums appear black and scabbed. Call your dentist to discuss it.
