What Wirecutter Tests in Whitening Strips
Wirecutter evaluates whitening strips based on ingredient safety, ease of use, sensitivity, and visible whitening. Tests include lab measurements and weeks of at-home use.
Top Wirecutter Whitening Strip Picks
Wirecutter's top whitening strip option is Crest 3D White Professional Effects, which uses hydrogen peroxide to remove surface and deeper stains. It earned a best pick for consistent results and manageable sensitivity.
