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.
Receding gums do not grow back. However, lost gum tissue can reconnect in the area of the gingival pocket (the pocket below the gums next to the tooth). This can prevent further gum recession. Gum tissue can only reattach if the area is healthy and free of gum disease.
