The SIS Building or MI6 Building at Vauxhall Cross houses the headquarters of the British Secret Intelligence Service (SIS, MI6). It is located at 85 Albert Embankment in Vauxhall, a south western part of central London, United Kingdom, on the bank of the River Thames beside Vauxhall Bridge.
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.
In advanced periodontal disease, gums recede and pockets form under the gum line, where bacteria move in and erode the supporting bone that anchors the teeth. Gingivitis is the mildest form and earliest stage of periodontal disease, and the only one that can be halted and even reversed with proper dental care.
