Mike, im thrilled to read one more arrow in the quiver of prevention. I do drink kefir in small doses when i have a bottle in the refridge.
Otherwise the fuzzy on my teeth is gone with low carb and brushing with baking soda. The fuzzy comes back and is a reminder i am off plan eating.

Listerine was poured down the drain some time ago.

With the overuse of antibiotics, interest in other methods of supporting a healthy microbiome thruout my body is an on going quest.

My SIL had thrush which lasted over a year....with conventional treatment. I often wonder if a faster option is possible to treat thrush. Like swishing with coconut oil or honey. As both are anti biotic and anti fungal.
