Gum Diseases

Black Spit



After flossing I had some bleeding. After rinsing my mouth with water I rinsed a second time with Listerine mouth wash. My spit was black. Why?


It is probably due to blood coloring listerine. It may also be smoking effect (if you are a smoker) or diet effect (coffee/tea etc. staining).
