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.
When your gums recede, they reveal the roots of your teeth -- but then they just keep on shrinking back. And, unlike nautilus and conch shells, the roots of your teeth aren't something anyone wants to display. Gingival recession, the term for receding gums, is more than an aesthetic issue.
