Crest 3D Whitestrips Kit Drops to $35 in Amazon Beauty Sale

Crest 3D Whitestrips Professional Effects, the popular at-home teeth whitening kit, are on sale for $35 on Amazon, down from a list price of $45.99 — a 24% discount and the product’s lowest price since January.

The kit includes 22 treatments, with each treatment made up of two strips: a longer one for the upper teeth and a shorter one for the lower teeth, for 44 strips total. Depending on the version purchased, the strips are worn for either 45 minutes or one hour and are designed to help remove surface stains caused by coffee, tea and other foods and drinks.

At $35, the kit is just above its all-time low price and sits near the bottom of its price history for the year, making the current discount one of the better opportunities to buy it in recent months.

What Buyers Report

Tooth sensitivity is among the most common complaints in customer reviews. Some shoppers describe discomfort after multiple treatments, while others note the strips can be tricky to apply or leave a lingering taste. Results also vary depending on the user’s teeth and the severity of existing stains.

“The sensitivity thing is real, and you do have to plan around that commitment,” one reviewer wrote. “But if you want results you can actually see without breaking the bank or sitting in a dentist’s chair, these are legit.”

“Around day six, I started getting these little zings of sensitivity in a couple of my teeth. Nothing unbearable, but definitely noticeable. Switching to Sensodyne toothpaste for a few days helped a lot,” another reviewer said. “If you’ve got sensitive teeth to begin with, you might want to do every other day instead.”
