Lasers vary in their use according to their wave length.
Coherent laser light is produced using carbon dioxide, erbium-Yag or Argon gases. Carbon Dioxide lasers are like tiny scalpels. They are very useful for bloodless surgery, speedier healing and finer control of soft tissue contours. Argon lasers speed the, bleaching processes and help set tooth colored fillings faster and harder. The Eribium - Yag laser is the first dental laser okayed by the FDA to begin work on teeth.
