We always want you to comfortably get the results you expect from previous applications, and we’re sorry to hear these were just okay! Please know that temporary sensitivity or soreness may occur with any product containing peroxide. The good news is we have tips and tricks to help reduce or even eliminate any discomfort for you. If you’re not in a hurry to whiten your smile we recommend waiting a day or two between applications or alternating between the top and bottom. This will make the whole process take longer, but it won’t affect the end results. We also recommend: -Be careful not to brush too hard, and avoid brushing more than twice a day. Use a soft-bristle toothbrush when using any whitening product. -Do not brush immediately before or after applying the Whitestrips. -Consider a mild toothpaste, there are many options specifically for sensitivity. We offer the Crest Gum and Sensitivity for relief within days that form a protective shield around your teeth and gums. Our Whitestrips also come in a variety of strengths, so we’d like to learn more about your experiences with our products so we can help further. Please give us a call at (800) 395-8423 and we’d be happy to help you get those results you remember!

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.
