We’ve seen too much laser destruction in movies that we end up with fear after even the slightest mention a laser going somewhere near our mouths. However, we usually forget that laser technology is actually highly effective in treating dental problems, that most dentists have been using laser technology as early as 1994. How Do Lasers Work? Lasers, an acronym of “light amplification by the stimulation emission of radiation” delivers energy and heat through light. Infrared light is easily absorbed by water. Since gum tissue primarily consists of water, thus it is highly effective in the uses of dentistry. When used for surgical purposes, the laser acts as a tissue vaporizer or cutting instrument. When used for “curing” purposes, it provides heat to strengthen bonds between the teeth and the filling.
