Again thank you for your insightful information and opinions. I was just reading up on how Cetylpyridinium Chloride works, and like you said, it adheres to the surface of the teeth creating a protective layer against bacteria and microorganisms. Along with using the ACT rinse, I also rinse with oil of oregano. 2-3 drops in a mouthful of water. I have found this to be successful in controlling and getting rid of my oral thrush that pops up every once in a while.
