Laser dentistry refers to the use of lasers to treat a variety of dental problems. In 1989, it was approved for use in clinical dental practice for procedures involving tooth tissue. When compared to drills and other non-laser equipment, laser dentistry may provide a more comfortable treatment alternative for a multitude of dental procedures involving hard or soft tissue. The abbreviation LASER stands for ‘Light Amplification by Stimulated Emission of Radiation.' There has been an explosion of laser application research investigations in the previous two decades. The use of a laser proved to be an effective technique for increasing dental treatment efficiency, specificity, convenience, cost, and comfort.
