Amazon Prime Day 2026 has officially arrived, bringing thousands of the deepest discounts of the year on all of the must-haves on your shopping list. And, among the best deals are some of the most popular (and dentist-approved) at-home teeth whitening kits, with discounts of up to 40% off.
Shoppers rave that Crest 3D Whitestrips are worth the investment even at full price, which makes this rare Prime Day discount an even sweeter reason to stock up. More than 70,000 shoppers purchased them in the past month alone, so you won’t want to wait too long to grab your kit. Prime Day runs from June 23 to June 26, giving Prime members just a few days to take advantage of the savings.
Here at The Post, we don’t just diligently fact-check to call out fake news — we also relentlessly price-check to get you inflation-beating bargains you can trust. Before we recommend a single Prime Day purchase, our experienced bargain hunters put every “deal” through our price-checking gauntlet:
The viral $30 Crest Kit includes 22 professional whitening treatments and, according to the brand, can help users “achieve up to 19 levels whiter teeth.” Reviewers seem to agree, with thousands raving about their “impressive” before-and-after results.
Said to remove up to 15 years of stains, these best-selling whitening strips offer an easy way to brighten your smile from your own home. No pricey dentist appointment necessary.

To use them, simply apply a strip to your upper and lower teeth, leave it on for 30 minutes, and remove. For best results, the brand recommends repeating the process daily for three consecutive weeks.
