Bump in area of extraction and implant placement surgery 6 weeks post back after being treated, what is this? (photo)

It
definitely looks like the area is infected. Bone loss is not a good
sign. Most likely the implant will have to be removed and the area
cleaned. It is
ideal to have a 3D scan taken to have a more accurate diagnosis of
bone loss. Then have the bone graft placed again and
let the area heal to make sure the infection is gone. After that a new implant can be placed. Getting a second opinion is always a good idea.

Hi, 
Sometimes post implant placement surgery, the area may get infected due to a number of reasons. 
Infection will cause bone loss around the implant and cause it to fail. 
Also since the implant does not have any nerve supply, there will be no pain or any other symptoms other than abcess formation. 
It is a good idea to see the doctor to get the implant removed. Also the area needs curettage and bone graft done. 
You will be able to place another implant in the future. 
Thanks
