We're glad you love your whiter smile, and would like to share some prevention tips if you're experiencing sensitivity. Our Whitestrips are very safe when used as directed, but like any whitening product that contains peroxide, temporary sensitivity may develop. First, don't brush too hard and or more than twice a day while using whitestrips. Also, avoid medium to hard bristled toothbrushes after whitening your teeth and instead choose a soft bristled brush. Trying a different toothpaste such as Crest Cavity Protection can also sometimes be helpful, as ingredients in some toothpastes can cause gum discomfort. If significant gum irritation develops, try using Crest Whitestrips only once per day, rather than two times per day or stop using for 2-3 days then resume once per day. Usually if you follow these tips, it should stop this problem from happening. If you still experience significant irritation, then we recommend you stop use. If you need any further assistance or have questions, please give our Crest Team a call at 1-800-395-8423 from 9AM -- 6PM EST Monday–Friday. We're always glad to help!

You deserve to shine a radiant smile, so we're sorry that you didn't get the whitening results you were expecting, Audrey! We have products for both intrinsic and extrinsic stains. Our Radiant Mint toothpaste works by removing those surface/extrinsic stains, but isn't able to reach those intrinsic stains. We think you may find more success with our Whitestrips and Whitening Emulsions since they can reach those intrinsic stains. We'd love to share more about these products, and learn more about your experience. When you're free, please call us at (800) 492-7378.

There's nothing more important to us than healthy and bright teeth, so we're sorry that you didn't get the whitening results you were hoping for, Daniel. Typically, these toothpaste can remove surface stains only. Some stains may be below the surface, and our Whitestrips and Whitening Emulsions are your best bet for removing those peskier stains. We'd like to hear from you about this, and we'd like to share more about these products with you. We can be reached at:,(800) 492-7378
