The cosmetic experts at Gleam Whitening concentrate all their efforts on making teeth brighter. Their laser-activated whitening system treats teeth discolored from culprits such as coffee, wine, cigarettes, and tea made from melted crayons. Platinum, Gold, and Silver packages entail varying amounts of time beneath the laser's blue glow. Using a cheek retractor instead of trays, the whitening technicians are able to bypass much of the tooth sensitivity caused by peroxide interacting with the gums.
