I would avoid alcohol containing mouthwashes, they are not the best way to kell off the negative flora in your mouth. Everyone know I';m a big Biotene person, especially their brand new line called PBF which not only has the enzymes but also a proprietary man made protein that eliminates biofilms in your mouth.

Along with alcohol killing off the GOOD flora in your mouth with the bad, which is a stpid idea when you think about it, it DRYS the crap out of your soft tissues, damaging them, especially in post treatment oral cancer patients.

If you do a bunch of research on jalapenos, hot sauces, and the hottest families of peppers in particular, they contain cancer fighting bio nutrients, and if you can tolerate them I would use them. This is not the same as chronic irritation in your mouth, which is mechanical for the most part not chemical.

Nice to see you back and in good health. And yes, our world is full of chemicals that might hurt us, but you can't avoid all of them. That is a fact that there is no sound way around to avoid the vast majority of them. Just remember to be prudent without being obsessive, and that the odds of dying on a CA freeway are pretty high compared to many of the illnesses that these things MIGHT cause. Everything in balance - include fear of that which might get you when you are not looking.
