Teeth staining



Hi. I`m in senior biology at schol and i am doing experiments on the effects of red wine, tea and coffee on teeth (rate of staining etc) i have my results but why do these three things stain teeth?


Teeth are porous and pick up stains, depending on how porous they are, from anything with color. The darker the liquid, the more capable of staining.
