Crest 3D Whitestrips Professional Effects ($30, originally $46)
These 3D whitening strips from Crest have been a customer favorite since the product's 2001 release, and for good reason. They contain hydrogen peroxide that achieves 19 levels of whiter teeth, providing results similar to a $400 professional treatment. One of our editors even used it on the journey to her wedding, and her teeth have never been whiter. Read more in our Crest 3D Whitening Strips review.
Editor Quote: "What truly impresses me about Crest 3D Whitestrips is how effective they are. Even though it had been well over a decade since I last used them, I couldn't resist trying them again and added them to my virtual Amazon shopping cart. The box boldly claimed they could 'remove over 15 years of stains in three days,' which initially made me a bit skeptical. However, the results speak for themselves." — Marisa Petrarca, contributing shopping editor
