I add 3-7 drops of oregano oil to sesame oil for oil pulling. helps so much. when this back tooth flares, I also pack it with aztec clay all around. clays good for digestive tract as well. I gargle with H.P.M. from the health food store -every day. for extreme infection, water pick w/ mms solution of 2 or 3 drops in warm water.
brush teeth with baking soda. it helps body to become more alkaline and it whitens teeth a bit.
the mercury in teeth must go at some point.
praying for you and me both to find the right, affordable dentist!
