gum operation

I forgot what the term was called (was it "grafting"?), but basically the specialist cut out a piece of gum from somewhere else and sew it to the gums of the teeth near the front, both top and bottom. It didn't really hurt at all but I was careful anyway. And for like 3 weeks or something, I did not eat anything solid. This was from around December 2005 to February 2006. Two separate operations.
