Function
-
LEDs used in dental offices work in tandem with the chemicals used for bonding and bleaching. To be activated, different resins and bonding materials may require a different intensity of light. Therefore, a dental office must choose the appropriate power of LED for each specific job.
Type
-
Dental LEDs use blue light. The dental materials used determine the intensity of light that must be used. According to a "Journal of the American Dental Association" article titled "Curing Performance of a New-Generation Light-Emitting Diode Dental Curing Unit," the blue light used in dental LED lights ranges from 400 to 500 nanometers.

Benefits
-
Dental LED curing lights work just as well as halogen curing lights, and they don't generate as much heat. Laser lights also produce more heat, which increases the potential for damage to gingival tissue and inner tooth soft tissue.
