Prime Big Deal Days is finally here, and bringing plenty of scores to smile about.
Along with a bevy of beauty staples, fashion finds and tech bestsellers, Crest 3D Whitestrips are on sale for Black Friday-level prices right now.
Plenty of stars swear by the at-home dental treatment for a camera-ready smile — including Erin Andrews, who told Page Six Style they’re part of her beauty regimen.
“[They’re] effective, budget-friendly and easy to use on the go,” she explained.
Fellow reality star Chrishell Stause told E! that they’re “quick and easy,” while Paige DeSorbo raved to the same outlet that they’re “better than going to the dentist.”
“I’ve used these since high school and they’re the best things ever,” the “Giggly Squad” co-host added.
The product’s also a longtime customer favorite on Amazon, earning it a 4.6-star average out of over 98,000 (!) shopper ratings. (Not to mention, it’s the No. 1 bestselling tooth-whitening strip on the e-commerce site.)

“Never disappoints, with daily use you will see a notable difference,” one satisfied shopper writes, while others call them “worth the price” and “amazing.”
Page Six Style & Shopping Director Elana Fishman also uses them twice a year, saying: “They definitely work — as well as a professional whitening treatment, in my experience. And importantly, my dentist told me they’re totally safe to use as an alternative.”
In addition to the classic version, the Crest 3D Whitestrips Sensitive White kit is also over 40% off right now.
