We’re sorry that you didn’t get the whitening results you were hoping for, and would like to help. 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, or extrinsic stains. However, stains can also get trapped below the enamel surface. These are called intrinsic stains, which are harder to remove with a whitening toothpaste. So that we can help you further, please give us a call at (800) 492-7378.<br />
