Crest 3D Whitestrips Glamorous White Teeth Whitening Kit with Hydrogen Peroxide - 14 Treatments

We're sorry to hear you didn't get the whitening results you were hoping for. Sometimes stubborn stains may require a second box of our Whitestrips to achieve the results you're looking for. So that we can help you further, please give us a call at (800) 395-8423.

We can certainly understand your disappointment with receiving Whitestrips that should be used in a short time-frame, and are happy to help. Our Whitestrips don't actually expire, they just have a best if used date. You can still safely use them after this date, however, they may be less effective. If you'd like to share more about your experience, please give us a call at (800) 395-8423.

It's great to know you're having success with the Crest Glamorous White 3D Whitestrips, Jennifer, and we appreciate your sharing this feedback. Please know we'd want nothing more than for you to get the brightest smile you can achieve, and while the whitening ingredient peroxide is at a level that is in line with regulations, some users may be more prone to sensitivity than others. This irritation is temporary and will subside, and there are steps you can take to reduce/eliminate this sensitivity, such as using a softer brush head when brushing after treatments. Also, although it may take longer to whiten, it is okay to use 3D Whitestrips over a longer period of time by waiting a day between applications or alternating between using the upper and lower strips. If sensitivity persists, please discontinue use and consult your oral care professional to see if there's a gentler kit you should use. We appreciate you choosing Crest, Jennifer, and if you have questions, don't hesitate to call us at 1-800-492-7378, M-F, 9 am- 6 pm EST.

We're glad you're noticing a whiter smile in just three uses! Still, having sensitivity isn't fun, and we'd like to share some tips that can help. Whitestrips are very safe when used as directed, but like any whitening product that contains peroxide, temporary sensitivity may develop. While using Whitestrips don't brush more than twice daily and brush gently using a soft bristled brush. Using a mild toothpaste such as Crest Cavity Protection is also a good idea. Another tip is to use the strips over a longer period of time by waiting a day between applications, or alternating between using an upper and lower strip. While whitening may take longer, you'll still have the same overall results. If you continue to experience significant irritation, then we recommend you stop use and consult your dentist. We'd like to follow up with you, and talk with you in more detail about your experience. Please give our Crest Team a call at 1-800-395-8423 from 9AM -- 6PM EST Monday–Friday.

We're so glad that our Whitestrips work for you, and that you're noticing a brighter smile! However, we're sorry to hear that you experienced sensitivity. While we do have safety checks, it's possible that you're more prone to the whitening ingredient peroxide. We're glad you found a way to reduce sensitivity, however, we want you to take full advantage of each strip. You can wait a day or two between applications, or alternate between an upper and lower strip. These tips may help, but we'd like to hear from you about your success and experiences. Please call us at (800) 448-6200.
