There are a couple of main issues associated with thin, fragile gums and dental implants. 1  The implant shows through the gums as a grey or grayish tint. This does not look good. 2  The gums can recede causing the bone to recede too. If this happens, the threads of the implant can show.
There are two components to your dental implant restoration â the implant that serves as your replacement root and the dental crown which serves as the prosthetic tooth. The dental implant can last forever. It is made of titanium and will fuse with your jawbone, allowing it to serve as a stable, functional root. It should not decay or corrode. In fact, some of the earliest dental implants placed over 30 years ago are still functioning properly in the mouths of these patients.
