You know, this is very strange, but I have been testing this on and off for a while now. When I floss, then brush, and then use a mouthwash right before I go to bed, I usually sleep more soundly and better. It is beyond weird, but, for me anyway, there just seems to be an unexplainable link which I have been trying to figure out.
Not strange at all. Those germs breeding in food particles lodged in teeth are doing a happy dance feasting. That wakes you up LOL.
