Tooth whitening is an increasingly popular cosmetic treatment. In surgery bleaching and dentist-prescribed, home-applied bleaching are the two most common procedures. Light activation using a range of light sources, halogen curing lights, xenon–halogen lights, plasma arcs, light emitting diodes (LEDs), LED plus lasers, and lasers have been used to reduce the bleaching time and decrease [read the full story…]
