Bren, we can certainly understand your disappointment with not achieving the whitening results you were hoping for.

You should certainly see the brilliant results of your Whitestrips after the full kit was used, Nicole. Our Quality Assurance team takes many steps to make sure of this when used as directed.

We understand the frustration in finding an almost-empty tube in your package, Cedric, and we assure you we want to help resolve this, as this is not typical and not the impression we want to leave with you. Our Crest Emulsions Kits undergo many thorough checks during manufacturing to meet the requirement, so we're not sure why this happened. We sincerely apologize for this mishap, Cedric, and you're welcome to use the Crest Money Back Guarantee to help with your purchase. You can find the information on the package or on our Crest website. If you need more help with this or have a chance to follow up on your case, please call us at 1-800-492-7378, M-F, 9 am to 6 pm EST.

Our Crest Whitening Emulsions are a leave-on treatment so it saddens us that yours won't stay on your teeth for 30 minutes. While it's normal for the emulsion to neutralize in the saliva over time, we would expect you to still experience a 100% brighter smile especially if your tongue doesn't come into contact with it, and you applied it to dry teeth. Let's get you the smile you deserve, when you have a free moment, give us a call at (800) 448-6200.

We're sorry to hear our Whitening Emulsions did not provide the whitening experience you had anticipated. Our products go through many quality checks to ensure they provide the experience you'd expect, so we will share this with our Quality team. With this product, it may help to completely dry your teeth before applying the whitening gel, and letting it air dry as much as possible after application. Whitening results can vary by each individual's whitening needs, but are typically noticeable after just a few uses. To learn more about our Money-Back Guarantee, please give us a call at 1(800) 395-8423.

Our goal is to leave your smile brighter, so we're disappointed to hear this. If you aren't in love with your results at the end of your kit, please reach out to us at (800) 566-7252, and we'll get more information to best help.
