While we're glad our Radiant Mint Toothpaste helped you get a brighter than ever smile, we're sorry to hear about your sensitivity. While we do have safety checks in place, it's possible that you may not tolerate this specific formula, so if sensitivity persists or becomes uncomfortable discontinue use and consult with your dentist. We have many different toothpastes we're sure you'll love, and we'd like to hear from you about your whitening success, and your experiences. When you have a moment, please give us a call at (800) 492-7378.

We're understand the desire for a white smile, and are glad you love the results. Whitestrips are very safe when used as directed, but it's true for some that some temporary sensitivity may develop. We'd like to share some tips that can help. First, don't brush too hard and or more than twice daily while using whitestrips. Also, choosing a soft bristled brush and a mild toothpaste such as Crest Cavity Protection can also be helpful. If irritation is noticed, it's okay to use 3D White Whitestrips over a longer period of time by waiting a day between applications, or alternating between using an upper and lower strip. Doing so will cause whitening to take longer, but with the same results overall with less risk of sensitivity. If you have any questions or concerns, we're always happy to help. You can give our Crest Team a call at 1-800-395-8423 from 9AM -- 6PM EST Monday–Friday.
