OP and everyone, many Thanks for the advice about oil pulling.
I'd read about it somewhere awhile ago, forgot it's name, and couldn't find it again so it wasn't thought of again, til now.
Coconut, Olive, Sesame, and Sunflower Oils are so delicious anyway it might be fun to try a different one day to day for variety. I almost said Walnut Oil too BUT - It might stain teeth because pulverized walnuts rubbed into dark hair can revitalize it when it's going grey, and make dark wood furniture look like new.
