Lasers have been used in dentistry since 1994 to treat various dental problems. Although the FDA has approved laser systems, none have received the American Dental Association's (ADA) Seal of Acceptance as an alternative to traditional treatments. This seal ensures that products meet ADA standards of safety and efficacy. The ADA is cautiously optimistic about the role of laser technology in dentistry. Lasers used in dentistry are different from cold lasers used for pain and inflammation relief. Some dentists use lasers to treat various conditions. Lasers work by delivering energy in the form of light. In surgical and dental procedures, lasers act as cutting instruments or vaporizers of tissue. In teeth-whitening procedures, lasers act as a heat source to enhance the effect of bleaching agents. Pros: Compared to traditional dental drills, lasers can be less painful, reduce the need for anesthesia, minimize bleeding and swelling, and decrease the risk of bacterial infections. They can also preserve more of the healthy parts of the tooth during cavity removal. Cons: The disadvantages of lasers include higher costs, the need for specialized training, and limitations in treating certain dental conditions. Lasers cannot be used on teeth with fillings already in place, and traditional drills may still be necessary for shaping fillings, adjusting bites, and polishing. Overall, while lasers offer several benefits, they are not a complete replacement for traditional dental tools.
