Laser stands for light amplification by stimulated emission of radiation. Lasers were first introduced for dentistry in 1988 and received FDA clearance in 1990. The effects of the light transmission vary by wavelength. This means that different types of tissue (hard/soft) absorb different wavelengths of light. In dentistry two types of lasers have been developed, hard tissue (teeth and bone) and soft tissue (gums, cheeks, tongue and lips). There are various procedures that each can perform.
The hard tissue lasers can re-contour bone and remove decay from virgin teeth. Sometimes this can even be accomplished without the use of anesthesia. The soft tissue lasers can accomplish a myriad of different procedures. Primary is that the laser light energy kills bacteria and virus. The single most important factor in stopping periodontal disease is the control of bacteria. Our hygienist routinely uses it after completing her cleanings to help the gums to heal most effectively. We have also used it to accelerate the healing of mouth sores (apthous ulcers) and herpes simplex. On these settings, the light is just waved over the area to kill the germs and also seal the nerve endings so that the discomfort from the sores is immediately relieved. Patients report that this is a Godsend. Lasers can also be used to re-contour gum lines for smile makeovers or frenectomies for individuals who are tongue-tied or have a large space between their two front teeth. I have seen this application used on newborns that were unable to latch and nurse. In less than a minute in the arm of the dentist and without the need for any anesthesia, the tongue was released and the child was immediately able to nurse. It was amazing to see and very heartwarming. The light energy at this wavelength is also capable of coagulating blood to stop any excessive bleeding and seal split lips. The bacterial elimination also contributes to better healing of surgical sites such as implant placement or gum surgery.
