A: While you shouldn't eat or drink (with the exception of water) while using our Crest Whitestrips, there's no particular foods or beverages that you have to avoid during the treatment period. It may be helpful to know that research shows our Whitestrips are effective for people who have stains from coffee, tea, dark sodas, red wine and even a few fruits and vegetables which are proven causes of discolored teeth. If you continue to use staining substances such as these, your teeth may discolor again.

A: While all our products are tested to be safe when used as directed, we recommend checking with your doctor before use.

A: The percentage is proprietary information, but you will notice great whitening results when using our Whitestrips as directed.

A: You can use our Crest Whitening Emulsions.

A: We recommend using a mild mouthwash or rinse like Crest Pro-Health Multiprotection or Scope Classic while you're whitening your teeth. If significant tooth sensitivity or gum discomfort develops, discontinue usage. To help maintain whiter teeth after using Crest Whitestrips, we recommend using a Crest Whitening Toothpaste and Crest Whitening Mouthwash or Rinse to gently polish away surface stains daily.
