Just wondering if the ones they sell at the stores work and if so, which brand(s) worked for you.

    Crest 3D whitening strips sold at Costco work for me. My teeth were noticeably whiter both times I’ve gone through a box. Of note, I drink espresso about 4 times per day, so maybe they’re particularly good at whitening coffee-stained teeth.

    They make my teeth sensitive after a few strips though, but sodium fluoride 1.1% toothpaste remedies that.
