Stains: Generally happen when the colored liquid attaches to a thin layer of plaque left on the teeth. Some people myself included can brush;floss drink a cup of coffee and the teeth look brownish so we rinse or brush again; its an enamel issue. Some people do not have this problem smooth less porous enamel.Red wine/tea will do the same thing or any colored liquid. No chemicals involved.
