It was my understanding that you can't do a gum graft over an implant as you need bone behind it. I have an exposed implant on my front tooth. I lost my tooth due to an accident.
Hi,
I think what is happening with your implants is what would happen if you had a healthy tooth there and not an implant anyway. Our gums have a tendency to recede. In all probability the reason you see the implant threads is because the gumline has receded back to your bone structure. Gum can't grow unless there is bone beneath it.
I don't know your age or the reason you got implants, but many receive them due to periodontal disease with resulting bone loss. Bone grafts alone would not be enough to keep healthy gums far enough down to cover many implants so the gumline recedes back exposing the threads. Just like it would the root of a natural tooth.
That said, there are ways to correct it. You can have a gum transplant graft. It is a surgical procedure, but those that have had it say it's not too bad. I have implants with exposed threads but decided not to do it. They take a patch form the roof of your mouth (think the worst pizza burn of your life, and multiply it by 10) and transplant the material to cover the implant then stitch it on. I understand the result looks very good.
I just keep my implants clean. My are my front top four and thankfully I do not have what is called a "gummy smile" so the exposed threads really don't bother me.
I think the surgery is a personal decision. I chose not to have it done. If yours really bothers you, you many ask about it.
Hope this helps.
My best to you,
Gellia
