Crest 3D Whitestrips Professional Effects Kit – 20 Treatments
We tested the Crest 3D Whitestrips Professional Effects Teeth Whitening Strips Kit and found it delivers noticeable whitening in just days. With 20 treatments (40 total strips), this kit promises professional-level results at a fraction of the cost—just $39.97. The advanced enamel-safe formula targets surface stains and deeper discoloration, making it a top pick for at-home whitening.
Why this teeth whitening kit stands out
After two weeks of daily use, we saw dramatic improvement. The strips adhere well and stay in place, so you can go about your routine. No messy gels or trays—just peel, apply, and wait 30 minutes.
💡 We found that using the strips consistently for the full 20 sessions yields up to 14 shades whiter, according to the brand—but even after 10 treatments, the difference is impressive. For best results, avoid coffee or tea immediately after removal.
