Gum graft showdown: which donor site heals receding gums best?

This study tested two different places to take gum tissue for grafting—the back of the mouth (tuberosity) or the roof of the mouth (palate)—to fix receding gums on a single tooth. Thirty healthy adults with gum recession received one of the two grafts along with a gum-lifting procedure. Researchers measured how much the gums grew back and how much pain patients felt over a year.
