Gum grafting (or gingival grafting) is a procedure performed to reduce or eliminate areas of gum recession by placing gum tissue overtop that will slowly heal the area. The gum tissue can be sourced in several different ways. Commonly, tissue was harvested from the roof of the mouth to be used for the recession site. This method causes an incision site on the roof of the mouth that can be painful and take time to heal. Alternatively, Alloderm gum grafting takes donor tissue that is altered in a lab to be used for the site of recession, significantly reducing pain and improving healing time.
