Brush your teeth thoroughly using SnapBright (twice daily, every day), or simply apply a generous amount to your finger and begin swiping your teeth. Then wipe away most but notall of the product with your wet finger as you will want to have some of the purple hues remain on your teeth for the whitening impact. Specification:
