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.
A dental implant replaces the natural tooth root and is placed into the jaw bone and is supported by the gum tissue. A tooth colored crown is placed on the top of the root to complete the restoration. Multiple single implants maybe placed into the jaw bone as a support for bridges or for a dental arch.
