I have gum disease and my teeth are starting to become loose. I started food grade hydrogen peroxide with a bit of baking soda. My tongue has turned black. Is this normal and am I doing it the right way. Thank you.
EC: Hi Fran, can you please tell us what percentage of food grade you used and whether you diluted it or not.
