Can I still use my regular toothpaste and mouthwash if I use Chlorine Dioxide rinse? No. Almost all commercial toothpaste's contain Sodium Lauryl Sulfate (SOAP), placed in toothpaste in order to create a foaming action, so that you think that something is actually happening. It has no beneficial effects at all. Unfortunately it will also inhibit the potency of the active ingredients. That is why those who use Oxyfresh toothpaste should read the ingredients in their toothpaste: It contains Sodium Lauryl Sulfate! Secondly, almost all mouthwashes contain alcohol. And as you know alcohol makes the mouth drier, which will then make the breath and taste worse. This will negate the benefits of the oxidation process.
