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.
