Toxic morning mouth occurs because of the body’s natural cleansing process that takes place while we sleep each night. From approximately 10pm to 6am our liver cleanses our blood. Many of the toxins and bacteria accumulate in our mouth. It’s not an accident that our breath is not its best first thing in the morning. Long ago, Ayurvedic practitioners observed this phenomena and recommended tongue scraping as a way to rid ourselves of yesterday’s toxins. EssentialOxygen Brushing Rinse operates on the same principle, but removes all of the bad bacteria, not just some of it.
