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 for "curing" a filling the laser helps to strengthen the bond between the filling and the tooth. when used in teeth whitening procedures the laser acts as a heat source and enhances the effect of tooth beaching agents.
