I had an implant done roughly a year ago and had multiple bone grafts prior to it. Unfortunately after months of checkups I was notified the implant did not integrate and has to be taken out. Is the implant placed too close to the adjacent tooth? Could that be the reason of failure, and is there any potential harm in the future to that adjacent tooth? I'm a little worried about taking this out because it's been a long time and I already have many small scars and a cleft on my gum from all the previous procedures. Any answers would be greatly appreciated!
