We're sorry you experienced sensitivity after brushing with our 3D White Radiant Mint toothpaste. Flavor oils, surfactants, foaming agents, tartar control agents, and abrasives all have some potential to cause irritation. To minimize these effects, don't brush too hard, more than twice a day and avoid medium and hard bristled toothbrushes after whitening your teeth. While all of our products are safe and effective, some people may not tolerate a particular formulation. If irritation persists or becomes uncomfortable discontinue use and consult with your dentist. Your satisfaction is very important to us, and we’d like to learn more about your experience to further help. Please give our Crest Team a call at 1-800-492-7378 from 9AM -- 6PM EST Monday–Friday. We'll be standing by.

We're sorry you're experiencing sensitivity to cold beverages after whitening. Whitestrips are very safe when used as directed, but with any whitening product that contains peroxide, temporary sensitivity may develop. Although harmless, we want you to enjoy a whiter smile without being uncomfortable, and would like to share some tips for preventing sensitivity. First, while using Whitestrips don't brush more than twice a day, and brush gently using a soft bristled brush. Using a mild toothpaste such as Crest Cavity Protection can also help. 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. Although whitening may take longer, you'll still have the same overall whitening effect. If you still experience significant sensitivity, then we recommend you stop use and consult your dentist. We'd like to talk with you in more detail about your experience to see how we can further help. Please give our Crest Team a call at 1-800-395-8423 from 9AM -- 6PM EST Monday–Friday. We're always glad to help!

We're sorry you had this experience with the Crest 3D White Professional Effects strips. Some users may be more prone to sensitivity than others and, as with any teeth whitening product containing peroxide, sensitivity or soreness may temporarily develop when using 3D White Whitestrips. The irritation is temporary and will subside, and there are steps you can take to reduce/eliminate this sensitivity. 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 will not cause a change in the overall whitening effect. It will also help to make certain not to brush too hard while whitening. If you have any questions, or if we can help you further, please give us a call at (800) 395-8423. We're here to help.
