If you are familiar with?

Hopefully you are familiar with the biotene products (mouthwash and toothpaste) and that it is used for sensitive mouths (and does not use harsh ingredients)....It has this enzyme in it that supports the body's natural saliva in the mouth to fight off bacteria and clean the mouth/teeth. However, I was wondering if it is ok to mouth wash or rinse with hydrogen peroxide as a gargle before using the toothpaste? Or would the hydrogen peroxide interfere with the biotene and it's natural enzymes and not work at all?? I do not know if anyone would know this but it would help a lot! Thanks!
