Crest Whitening Strips, particularly the Gentle Routine version that can be purchased from The White Smiles, are an accessible at-home whitening alternative. Sensitive teeth were considered while designing these strips, and the enamel-safe formula penetrates to gently removes years of stains from coffee, wine, smoking, and aging. The active ingredient, hydrogen peroxide, whitens from beneath the enamel and is gentle.

What is unique about these strips is the Advanced Seal™ Technology that gives the strip a no-slip grip - meaning you can talk, walk, and even drink while you're whitening! Each strip molds comfortably to your teeth and peels off entirely keeping it neat and tidy! Typically, users see visible results within a couple days and the full whitening effects appear around the 10th day of consistent use for 30 minutes.

The White Smiles sells the strips in various quantities and also offers quick shipping and is free on larger orders. For a better outcome, Crest also recommends you use Crest's Gum and Sensitivity Whitening Toothpaste. Together, you not only receive more whitening power but also maintain your oral health and stop new stains from forming!
