After undergoing a self-application whitening treatment with Radiant Smiles Pro, teeth shades will brighten typically 6-10 shades. Individual results will depend on your current tooth shade, treatment time, and the composition of your teeth. Your end result will be a whiter, healthier smile. Everyone’s teeth are different and will have a natural stop point. We recommend a 60 minute session for optimal results and to remove all layers of staining.
