The term LASER means “light Amplification by the Stimulated Emission of Radiation’. The application of LASERS in dentistry was first done by Miaman in 1960. Since then LASERS has seen many applications in dentistry. Use of LASERS in dentistry has proved to be an effective tool to increase efficiency, specificity and ease of treatment for the patients. LASERS are used in both soft tissue and hard tissue treatment procedures.

How do LASERS work in dentistry?
All LASERS work by delivering energy in the form of light. When used for surgical and dental procedures, the LASER acts as a cutting instrument or a vaporizer of tissue that it comes in contact with. When used in teeth-whitening procedures, the laser acts as a heat source and enhances the effect of tooth-bleaching agents.
