Off the top of my head I'd recommend drinks high in chlorophyll such as green smoothies, or even liquid chlorophyll in water or juice. Essiac and other teas, yes. Camomile would be good.
I had gum disease and UT has helped me, it will help you too!
Try putting some propolis tincture in the urine, it will boost the effects greatly.
By the way, it seems to me that your post would be more appropriate in the Urine Therapy Support forum.
