Years of coffee, tea, wine, and everyday foods cause deep intrinsic enamel staining that standard whitening toothpastes and mouthwashes simply cannot budge. Crest 3D Whitestrips Professional Effects provides a professional-level, dental-grade teeth whitening system that delivers visible results in just 3 days and removes over 14 years of stubborn stains in 20 days.
Formulated with the exact same enamel-safe hydrogen peroxide whitening agent used by dental professionals, these strips safely penetrate beneath the porous enamel layer to oxidize and erase deep-set discoloration. The proprietary Advanced Seal Technology ensures the strips conform precisely to the shape of your teeth and grip firmly, allowing you to talk and drink water while whitening without slippage.
This complete kit includes 20 Professional Effects treatments (applied for 45 minutes daily) plus two bonus 1-Hour Express treatments for rapid same-day brightness before special events. It is the #1 dentist-recommended at-home teeth whitening brand, validated by the American Dental Association (ADA).
