Gum Grafting Family Dentistry & Orthodontics In Sterling, VA There are two types of gum grafting: free gingival graft and connective tissue graft. Each serves a specific purpose in treating gum recession. Our periodontist will recommend the treatment that is right for your individual needs. Free Gingival Graft: this graft is designed to thicken thinning gums in cases where there is no tooth root exposure. By thickening the gum tissue, your gums are more resistant to infection. Additionally, the free gingival graft helps to prevent further gum recession. Connective Tissue Graft: this graft is designed to treat cases where tooth root surfaces have been exposed. The graft is used to cover the exposed tissue and help to reestablish the proper gum contours within the mouth. The success of this method often depends on the amount of bone loss in the area where the exposure has occurred. Our doctors will discuss your benefits and likely outcomes prior to beginning treatment.
