A protective shield is substantially preformed to fit within a mouth of a patient undergoing high or low intensity pulse light or laser treatment to prevent pain from developing the nerves or because of the presence of metal dental work. The shield will diffuse the laser beam to thereby lessen or prevent any impact on the nerves. The shield can be made of a plastic material such as Ether Polyurethane, Polyethylene Teraphthalate, Polyethalyne, and/or Polycarbonate.
