Gingival melanin hyperpigmentation, though physiologic, often represents an esthetic concern, especially among patients with high smile lines. This case series evaluates the clinical effectiveness of the Wiser2 diode laser (980 nm) for gingival depigmentation. Multiple patients presenting with diffuse anterior gingival pigmentation were treated under topical anesthesia using 2% Xylocaine gel, with a power setting of 1.5 W in continuous mode. The procedure was minimally invasive, bloodless, and well tolerated. Rapid healing was observed within one week, and a uniform coral-pink gingival color was achieved within two to three weeks. Follow-up at one, three, and six months demonstrated stable esthetic results, absence of repigmentation, and high patient satisfaction. The diode laser’s strong absorption by melanin and hemoglobin provided precise epithelial ablation, effective hemostasis, and minimal postoperative discomfort. Within the limitations of this case series, the 980 nm diode laser proved to be a safe, predictable, and efficient method for the esthetic management of gingival hyperpigmentation.
