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.
This actually means that a dental implant failure may occur whenever the implant doesnât establish a direct structural and functional connection with a living bone. In most of the cases, symptoms of dental implant failure will involve redness, inflammation and the puffiness along the gum, at the base of implant. In some cases, bone or cum recession or erosion may also be present. An occurring infection at the spot may also indicate the dental implant has failed.
