The word laser is an acronym for “light amplification by stimulated emission of radiation”, which means that the intense and narrow beam of light is of one wavelength. Lasers revolutionized many surgical procedures, minimizing bleeding, swelling, scarring and pain. The potential benefits of laser use in dentistry include procedures done on soft tissue of the mouth with patrons reporting less postoperative pain. Laser surgery seals off nerve endings, so recovery is less painful, because the laser also seals off blood vessels which would bring clotting and other factors to help heal the tissues.
Laser teeth whitening is the wave of the future (as is laser dentistry, in general). In just one appointment your teeth can lighten anywhere from 5 -10 shades. Lasers were developed for teeth whitening in response to consumer complaints that traditional bleaching was too painful and resulted in inflammation. Lasers, on the other hand, can be focused on a very specific area to avoid these effects. No matter what the application, laser technology seems to be perceived as better and more effective than traditional therapies; because of the intensity of the laser, the total tooth exposure time is less than with a bleaching light and curing light, keeping the tooth cooler during activation. Cooler teeth are less likely to be sensitive; with less sensitivity, more bleaching can be done at each immediately.
