after brushing flossing and routinely cleaning the mouth with either a few drops of cinnamon oil/ clove oil..... a few drops of food grade hydrogen peroxide..... peppermint oil..... baking soda (these aren't all at once, these are just different remedies done on their own ) then the last step is MYRH OIL. it cures halitosis. I cured my old baby tiny chihuahua EXTREME sewer mouth from rotting teeth (I got her this way) with putting MYRrH OIL in her mouth daily. it was a MIRACLE CURE and on the bottle it says it cures types of skin fungus, halitosis. Acne etc.
