There are a couple of problems that you can have with dental implants. The first problem is that the implant can eventually become loose and fall out. This can happen because the implant material begins to deteriorate over time (from bacteria or other factors) or the implant may simply become loose in the jawbone. If this happens, it may need to be replaced with a new implant.Another potential problem with dental implants is that they can sometimes undergo local infection after beingplaced into your jawbone. If this infection becomes severe, it may necessitate removal of the implant and further treatment.
