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.
Case 1: Overgrown Gums (Altered Passive Eruption) The gums normally recede as a part of the normal eruption of the teeth. This is called passive eruption since the teeth aren't really moving or erupting, but the receeding of the gums creates the impression of active tooth movement. The teeth are usually not too short, they are usually normally-sized.
