Thank you for sharing your concerns, Hilary. We recommend reaching out to Sam's Club and sharing your experience. You can reach them by calling 1-888-746-7726.

We're sorry this has been your experience, since we can assure you that we have many quality checks in place to ensure that you can enjoy the best possible results with our toothpastes. As well, a lot of thought goes into creating features that we think you'll like. If you're experiencing aftertaste, we recommend discontinuing use of the product, and it may be helpful to know that there are different kinds of whitening when it comes to oral care products. Most toothpastes work to remove the stains on the surface of the teeth.. However, stains can also get trapped below the enamel surface. We'll be sharing your feedback with the rest of our team, and we'd also like to gather some more details for our Safety and Quality Teams. When you have a chance, please give us a call at (800) 492-7378.
