They say you can get rid of a myriad of diseases by OP, but I haven't experienced any thing different except for my gums and teeth. I'm sure it will draw bacteria from the mouth so that it doesn't get into the body,
I only do it in the morning, but I guess others do it more often. I think that my teeth are whiter, but I also use a herbal teeth whitening tooth paste too. The main thing is it has helped my gums, and it cleans the food particles that can get trapped in the teeth that brushing doesn't get.
Apparently it keeps the plaque from forming on the teeth as I notice my teeth cleanings at the dentist are very short compared to before I was doing the OP.
