We're very sorry you had this experience. We want you to love the benefits and the taste of ourCrest ProHealth Advantage Rinse. While we completely understand that taste preferences are very subjective and personal, we'll make sure to pass you comments on to our teams. If you have any questions, please feel free to give us a call at (800) 285-9139.

We're so sorry this happened to you. Please know that your safety is our top priority, and while clinical studies show our products are safe, this can happen for a small percentage of people. Oral care products such as Pro-Health Rinse contain CPC, which may cause a temporary aftertaste or temporary change in the taste of food. We'd like an opportunity to speak more and have our teams review your case. Please discontinue using this mouthwash, and please call us at 1-800-492-7378, M-F, 9 a.m. to 6 p.m. EST, for further assistance.

We’re sorry to hear that was your experience, we always want you to get lasting freshness but not a taste that lasts for days. Please know all of our products are thoroughly tested to be safe to use, and our Pro-Health Rinse doesn’t cause permanent taste alteration. An ingredient in this rinse, CPC, may cause a temporary aftertaste in a small percentage of people. We recommend Crest Bacteria Guard + Alcohol, which offers anti-plaque and anti-gingivitis benefits without the ingredient that didn’t agree with you. Please give us a call at (800) 285-9139 and we’d be happy to help further.
