Just when I thought at-home whitening meant pain and sensitivity, Made by Dentists proved me wrong. Their whitening powder-with micro-fine PAP, hydroxyapatite, and diamond powder-instantly lifts stubborn stains without abrasiveness or enamel damage! I've been using it for about a week, and my smile is visibly brighter-and my sensitive teeth haven't flinched a bit! LTKBeauty LTKHome LTKFindsUnder50
