We’re sorry to hear you didn’t get the whitening results you were hoping for. There are different kinds of whitening when it comes to oral care products. Our mouthwash works to remove the stains on the surface of the teeth, or extrinsic stains.  However, stains can also get trapped below the enamel surface.  These are called intrinsic stains, which can be removed using other whitening products, like our Whitestrips. So that we can help further and learn more about your experience, please give us a call at (800) 285-9139.
