I used "HealThy Mouth Blend" essential oil and homemade kefir for a mouthwash. Fixed my gums and banished my chronic tooth staining and bad breath in about three months.

The clove and other oils disrupt bacterial plaque formation, and kefir is an natural antibiotic. That's why it does not spoil. It also colonizes the GI tract over time; crowding out 'bad bugs' down there just as it does in the mouth. That's my theory as to why it works so well when low-carb alone did not.
