This isn't the refreshing clean we'd expect, which is why we'd like to follow-up with you to gather as many details as possible for our Health and Wellness team. In the meantime, we do want to share that the active ingredient in Crest Pro-Health Rinse has been recognized as safe and effective by an FDA advisory panel, as the label meets current FDA standards. The temporary aftertaste, or change in the taste of food, that a small percentage of consumers might experience, typically goes away shortly after you stop using it. So we can learn more and help you rinse your way to a healthier smile with the right mouthwash for you, could you please give us a call at (800) 285-9139?

We're sorry this was your experience. Since safety is our top priority here at Crest, we can assure you that our products have been thoroughly evaluated to be safe when used as directed. Certain versions of our Crest Pro-Health Rinse contain cetylpyridinium chloride (CPC), an ingredient that not only helps to fight plaque and gingivitis, but also kills bacteria in the mouth. For a small percentage of people who use the product, after it kills germs in your mouth, those dead germs can collect on the tooth surface and create the appearance of brown stains. This is reversible and largely preventable. To help remove and prevent the discoloration, we recommend a tartar-control/whitening toothpaste, a power toothbrush, and flossing. Any remaining stains can be removed with dental cleaning. We'll be sure to share your comments with our team. We'd also like to gather some more details for our Safety Team, so please give us a call at (800) 285-9139 when you have a moment.
