Calculus is most commonly found on the lingual surface of these teeth, so they are subjected to inflammatory elements resulting in tissue deformation and destruction. Significant attention has been paid to grafting the buccal surface, but there is a paucity of information addressing the lingual surface of mandibular anterior teeth. Gingival augmentation procedures are essential before fixed restorative dentistry to prevent further recession and facilitate plaque control.
