Replace 10-Year Old Implants?

I have two implants, located on either side of my two front teeth, that are 10 years old and I’m curious when or if I will need to replace them. I have some gum recession around both of them now, although one implant had gum recession almost immediately after the procedure was complete and continued to recede even after a gum graft. Aside from the receding gums, my implants appear to be healthy and secure but I am worried about bone loss due to the gum loss. I am wondering if another gum graft would help slow down any pending bone loss or if complete replacement of the implants is the only course of action.
