Smiles marred by drinking coffee, tea, and wine or smoking brighten two to eight shades under the ministrations of Smile Labs of Boise, a center specializing in teeth whitening. There, patients paint their own smiles with Applia-Brush gel, a hydrogen peroxide-based formula that hydrates teeth more effectively than showering with an open mouth. Cold blue light from an LED lamp then activates the photosensitive gel, accelerating the whitening process so teeth can achieve the perfect snowy color in 15 minutes.
