Notice how ClO2 works on anaerobic bacteria:
CloSYS® will prepare your teeth for brushing. This pH
neutral rinse ensures that brushing teeth does not occur in
an acidic mouth. If your mouth is acidic your teeth will be
soft and easily damaged by the abrasiveness of toothpaste.
CloSYS® works on oxygen-hating disease bacteria, to
improve gum health, safely and gently. CloSYS® reduces
99.9% of harmful bacteria in your mouth, specifically the
ones that cause bad breath and gum disease.
