Why We Picked Crest 3D Whitestrips Professional Effects
- A full 22-treatment course. With 44 strips covering 22 treatments, this kit is built for a complete teeth whitening routine rather than a short trial pack.
- Enamel-safe hydrogen peroxide formula. The brand positions this as enamel safe whitening, using hydrogen peroxide as the sole active ingredient rather than a blended, less-studied formula.
- The clear category leader. A 4.6-star average from 105,686 ratings, the #1 Best Seller ranking in Teeth Whitening Strips, and over 100,000 units sold in the past month make this the most purchased option in the category by a wide margin.
Key Ingredients and Features
Hydrogen Peroxide Whitening: the single active ingredient behind the formula’s professional teeth whitening strips positioning, working to lift stains from coffee, tea, and wine.

19 Levels Whiter Claim: the brand states this system can whiten teeth up to 19 shades, framed by Crest as professional-level results achievable at home.
Long-Lasting, Stain-Removal Claims: the brand states results can last up to 12 months and that the formula removes up to 14 years of stains, positioning it as a long lasting whitening option rather than a short-term fix.

Pros and Cons
Pros
- Exceptional review base: 4.6 out of 5 stars from 105,686 ratings, ranked #1 Best Seller in Teeth Whitening Strips
- Full 22-treatment, 44-strip kit for a complete at-home whitening routine
- No-slip grip strips designed to stay in place during wear
- Gluten-free, nut-free, and soy-free formula
Cons
- Hydrogen peroxide-based whitening can cause temporary sensitivity for some users, which is a common consideration with any peroxide strip and worth expecting going in.
- At $0.80 per strip before the current discount, this runs pricier per treatment than some peroxide-free or lower-treatment-count alternatives.
How It Works and What to Expect
This system uses hydrogen peroxide as its sole active ingredient, applied through a no-slip grip strip designed to stay adhered through a full treatment without sliding. Crest positions the formula as capable of whitening teeth up to 19 shades and removing up to 14 years of built-up stains, with results the brand states can last up to 12 months when paired with normal oral care. As with any at-home whitening treatment, actual results depend on the type and depth of existing stains, and the full benefit of the 22-treatment course is generally realized by completing the entire regimen rather than stopping early.
Best For Teeth Whitening Goals
- Anyone dealing with visible coffee, tea, or wine stains looking for professional teeth whitening at home
- Yellow teeth that haven’t responded well to whitening toothpaste alone
- People who want a full 22-treatment course instead of a short trial-sized kit
- Shoppers specifically comparing professional level teeth whitening options against in-office treatments before committing to either, since Crest 3D Whitestrips Professional Effects is positioned as an at-home alternative to a dental visit

Quick Q&A
How many treatments come in this kit? The kit includes 44 strips, covering 22 total treatments for a complete at-home whitening routine.
What is the active ingredient in these whitening strips? Hydrogen peroxide is the sole active ingredient, which Crest positions as enamel-safe when used as directed.
How long do results last? Crest states results from this system can last up to 12 months when paired with a normal oral care routine, though individual results vary based on diet and habits like smoking or coffee consumption.
What Shoppers Are Saying
This kit holds a 4.6 out of 5 star average from 105,686 ratings on Amazon, with more than 100,000 units purchased in the past month and the #1 Best Seller badge in Teeth Whitening Strips. That combination of an exceptionally high review count and consistent, large-scale purchase activity points to a genuinely trusted, category-leading product rather than a newly popular trend.
How to Use and Care Tip
Apply one strip to the upper teeth and one to the lower teeth, pressing firmly along the gumline for the no-slip grip to hold, and complete all 22 treatments in the kit for the full whitening effect rather than stopping partway through. Avoid drinking coffee, tea, or red wine immediately after a treatment, since freshly whitened enamel can be more prone to picking up new surface stains right after each session.
