Soft tissue health and esthetics are important factors in achievement of an attractive smile. The relationship between periodontium and restoration is critical if gingival health and esthetics are the goal. Current use of lasers in esthetic dentistry includes a wide variety of soft tissue procedures. Numerous wavelengths are used, and their specific use depends on different tissue absorption characteristics. When laser surgery is considered, it is important to follow the same principles as in conventional periodontal surgery. The zone of attached gingiva, alveolar crest position, gingival sulcus, epithelial attachment, and periodontal ligament must be taken in consideration. This article discusses use of a CO2 laser in soft-tissue management of diastema closure and gingival hyperpigmentation. We will demonstrate how CO2 laser can be used to manage the soft tissues in association with the restoration to improve esthetics.
