The details

The Crest 3D Whitestrips Professional Effects teeth whitening kit promises to get your teeth 13 levels whiter in just 22 days. The kit comes with 22 treatments in larger sizes than previous versions.

Crest uses the same whitening ingredients as professional dentists to brighten your smile, and the Canadian Dental Association has validated its strips.

Crest Whitestrips are effective and safe on enamel and feature a no-slip grip, allowing you to talk and even drink water while whitening your teeth.

What people are saying

The "Amazon's Choice" Whitestrips come backed by more than 3,400 reviews from shoppers, with an average rating of 4.5 stars.

One reviewer says they saw a "noticeable difference" after completing the kit's 22 treatments and calls it a "great product."

"[I'm] absolutely impressed" and "noticed a difference after [the] first use."

These "100 per cent work," says another reviewer. They are "amazing," and you will see a "noticeable difference" after using them. Adding, "my dental hygienist even complimented me on how white my teeth are."

While Crest's whitening kit has earned top marks for flavour, ease of use, and its ability to whiten, some reviewers say the new larger strips cause "gum sensitivity and pain."

"[I] had no issues" with the smaller strips, writes one shopper. However, the new larger strips "burn my gums."

The verdict

A shopper favourite, Amazon reviewers give a smiling approval to the Crest 3D Whitestrips Teeth Whitening Kit, calling it an "amazing" product that delivers "noticeable results." And it's a great time to add it to your cart while it's on sale during Amazon's Big Spring Sale. However, some reviewers experienced gum pain and sensitivity with the new, larger Whitestrips, which is something to keep in mind when placing your order.
