Gingival recession is a common complication during orthodontic treatment that causes root dentin hypersensitivity, root caries, loss of periodontal support, and food impaction, and it may affect the appearance of patients. Gingival recession is caused by multiple factors, and it usually occurs in the anterior teeth and left side of the mandible. Gingival recession is divided into four classes. More than 50% of the healthy population have gingival recession and the degree of gingival recession is aggravated by increasing age. The preferred treatment for gingival recession is nonsurgical and involves controlling inflammation, occlusal grinding, and removing the etiology of food impaction during and after orthodontic treatment. The surgical methods include soft-tissue grafting through flap transplantation and guided tissue regeneration through regeneration of periodontal tissue. Gingival veneers can be used to restore the shape of the gingiva if nonsurgical and surgical methods are ineffective in physiologic gingival reconstruction.
