A gingival graft stabilizer has an elongate member and slanted arms extending from opposing ends of the elongate member. An anterior guide extends from one of the arms and a posterior guide extends from the other arm. The anterior guide includes spaced protrusions extending from an upper end of the anterior guide. The posterior guide includes spaced protrusions extending from opposing sides of the posterior guide. During suturing of a gingival graft, a dental surgeon holding the elongate member can stabilize and position a gingival graft on anterior gingiva using the anterior guide or on posterior gingiva using the posterior guide. Sutures can be made in the spaces between and around the protrusions of the anterior guide or the posterior guide.
