Blane, we&#39;re sorry to hear this mouthwash left a bad aftertaste, and would like to help. Pro-Health Rinse does not cause permanent taste alteration. Oral care products containing CPC, an ingredient in Pro-Health Rinse, may cause a temporary aftertaste or temporary change in the taste of food in a small percentage of people, and can stay in the mouth for long periods of time. Aftertaste/change in the taste of food typically goes away shortly after you stop using the mouthwash. So that we can help you further, please give us a call at (800) 285-9139.<br />
