The role of lasers in cosmetic dentistry.

Dental lasers contribute significantly to the field of cosmetic dentistry, providing an invaluable resource for clinicians who perform different types of esthetic procedures. Practitioners in this specialized field not only help patients acquire beautiful and ideal smiles and dental health, but also they assist patients in benefiting from tremendous clinical advantages, such as sterile surgical sites and increased comfort levels. Tooth whitening will always be an important component of cosmetic dentistry. Developing the most efficient and safe method of tooth whitening is the goal of power bleaching. Currently the argon laser has proved to be the most valuable energy source for power bleaching. Clinicians need to learn more about constantly updated technology and apply newly discovered methods and protocols to clinical situations to benefit patients and clinicians.
