Crest Whitening Kit Sees $20 Discount Ahead of October Prime Day

A popular at-home teeth whitening solution, the Crest 3DWhitestrips + LED Light Teeth Whitening Kit, is available for $20 less than usual through an exclusive coupon on Amazon. This offer precedes the official October Prime Day event, which is scheduled for Oct. 6 and 7.

The dual-action kit is designed to help users achieve up to 34 levels of whiter teeth, according to the brand. Many reviewers have reported significant improvements in as little as a few sessions, with some stating it's "seriously effective."

The Crest 3DWhitestrips Professional Effects + LED Light kit utilizes professional-grade hydrogen peroxide within its Advanced Seal Technology, which aims to keep the strips in place for up to 60 minutes without slipping. This allows users to talk or drink water while the treatment is in progress. The included LED Whitening light is intended for use after the strips to enhance the brightening effect.

Thousands of customers have shared positive feedback, with many noting that they had previously tried various whitening methods without success. One reviewer mentioned that their dentist had informed them that some individuals have naturally yellow teeth that are resistant to bleaching. "I thought I’d try using a purchased whitening system one more time before giving in and dropping a bundle at the dentist’s," the reviewer stated. "Much to my relief, these strips actually whitened my teeth to a shade where I can really tell a difference. I’m so relieved and not ashamed to smile anymore."

The kit contains 20 whitening treatments, each with one upper and one lower strip, along with the LED light. Users have found the system to be simple and convenient, with the results deemed worthwhile, especially when purchased during a sale.

The offer, which provides a $20 discount, expires at the end of the current month. This promotion allows shoppers to acquire the kit ahead of the larger Prime Big Deal Days event.
