Can an implant be rejected?

Yes. Implants can be rejected, but not in the way we know "rejection" can occur in organ transplants, like with kidneys and hearts. We know dental implants are bio-compatible. There are no known allergic reactions to commercially-pure, titanium implants. which are the most prevalent kind used today. But failures do occur.

According to dental implants new york the failures we see in dental implants can be explained more in theory, than in fact. For instance, bacteria can contaminate implants. When this happens, an infection might cause the implant to be lost. Naturally, great efforts are taken to insure sterile conditions during implant procedures, from the way the implants are packaged to the hygienic conditions in the operating room.

But a curious fact exists: when an individual has many implants placed, why does only one fail, for example, and all the others "take?" What was different about the one that failed? Probably nothing. What we have come to believe is that the single greatest cause for dental implant failure is that bacteria are already in the jaw bone "before" the implants are placed. The implant passes through this bacteria-laden bone, like smashing through a bees’ nest, and that the seeds of implant failure have been sent into high gear. When this happens, it could take a week or a month, or even half a year, before the implant fails.
