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.
The situation of receding gums happens when the tissue of the gum around the teeth corrodes and it looks like your gums recede backwards. Then a large surface of the teeth is exposed and more visible. When the gums go back, the space between the gum line and the teeth rises. That is perfect place for bacteria growth.
