Gingivectomy is the most common procedure performed with dental lasers. All laser wavelengths can be used to precisely incise gingiva for restorative, cosmetic, and periodontal indications. Rapid healing and reduced pain are commonly seen post operatively and patients rarely need periodontal packing or sutures. The thermal effects of diodes, Nd:YAG and CO2 lasers must be understood to avoid collateral damage, but in properly trained hands these devices are quite effective. Erbium edlasers pulsed technology, shallow penetration, and water absorption produce a minimal thermal effect and minor procedures can sometimes be achieved with no anesthetic at all. The nearly "cold cutting" effect of erbium tissue interaction creates a remarkable post-operative course.
