Lasers are the latest and the most successfully introduced technologies in dentistry. Laser dentistry can be a precise and effective way to perform many dental procedures. The potential for laser dentistry to improve dental procedures rests in the dentist's ability to control power output and the duration of exposure on the tissue (whether gum or tooth structure), allowing for treatment of a highly specific area of focus without damaging surrounding tissues. Over the past four decades, various wavelengths have been successfully used in dentistry. The application of lasers is wavelength specific and depends on its absorption and interaction in different oral tissues. With the help of lasers, the dentist can enhance the patient’s esthetic appearance keeping in mind the tooth and tissue interface in a harmonious manner. Lasers have therefore been a great boon for the creation of gum and bone contours necessary not only for aesthetics but also for proper functioning of the concerned tooth/teeth. As the applications for dental lasers expand, greater numbers of dentists will use the technology to provide patients with precision treatment that may minimize pain and recovery time.
