It breaks our hearts to hear your teeth whitening was this painful, and we're sharing your feedback with our Safety Team to review. We assure safety is at the top of our priority list when designing products to give you the bright smile you desire, and while clinical studies and consumer tests show our Whitestrips to be safe and effective, some consumers may be more prone to sensitivities than others. We're sorry this happened to you, and we'd like an opportunity to learn more about your experience and make this right. Please call us at 1-800-492-7378, M-F, 9 am to 6 pm EST.

We're sorry to hear the Crest 3D Whitestrips didn't provide the whitening experience you'd hoped for, Anasia. Our whitening products undergo many quality checks to ensure they deliver the experience you'd expect, so we will be sharing your feedback with our Quality team. To help us learn more about your experience, please give us a call at 1(800) 395-8423.

We’re sorry to hear that, William, we always want you to be impressed with our Whitestrips. We do offer the Crest Money Back Guarantee, and we’d love to learn more about your whitening goals so we can help you achieve them. Please give us a call at (800) 395-8423.

We always want our Whitestrips to make your smile nice and bright, so this makes us sad to hear. Your health and safety is extremely important to us, and we'd be happy to help, Yegehehr. As with any teeth whitening product containing peroxide, sensitivity or soreness can happen, but is temporary. If you haven't done so already, we'd recommend not brushing too hard more than twice per day, and using a soft bristled brush during your whitening treatment. We'd love to learn more, and gather some further information for our Safety Team. When you have a second, we hope you'll give us a call at 1-800-492-7378.

We're sorry to hear this, Paulie. We can assure you that our products go through strict quality checks to ensure that they reach you in the best possible condition. It may be helpful to know that this Whitestrips product is intended to ship with the sachets in a cardboard box. We'll be sure to let our team know how you feel, and you can give us a call at (800) 395-8423 if you have any further questions.
