Super-Sale Alert: The Crest Whitestrips featured in this story are 27% off ahead of Prime Day! For more insider information on Amazon Prime Day, consult our Shopping team’s curated guides to the deals that matter here.

Crest Whitestrips are the unofficial (but nevertheless uncontested) star deal of Prime Days past — and for good reason. The highly rated teeth-whitening system rarely gets more than a paltry discount; however, Prime sales are the rare times when Crest Whitestrips reliably go for under $40 — a serious steal, if you ask us.

The early Prime Day deals are here, and Crest Whitestrips are part of the drill. The brand has a few kit options to choose from, in addition to a smattering of coupons on other items like toothpaste and mouthwash. Most notably, there are the 1-Hour Express Whitestrips, marked down to $31.99, which boast over 1,500 reviews as of press time. If you want to more closely mimic the in-office experience, there is the Crest Whitening Emulsions Leave-on Teeth Whitening Gel Kit With LED Accelerator Light, to help achieve your brightest pearly whites ever.

Crest 3D Whitestrips 1 Hour Express, $54.99 $31.99

Crest 3D Whitestrips Glamorous White, $40.68 $33.80
