Teeth are not naturally as white as the advertising would have you believe. They are mostly bone white which is a an off color shade of white(slightly towards brown). Why some peoples teeth seem whiter than others may be more to do with the contrasting background (skin color being darker). Not saying your teeth are not porous. They will absorb stains such as tea, coffee, kool-aid and bleaching chemicals. So, if you abstain from the staining chemicals and have a healthy diet (low on sugar and decent amount of calcium it is about the best you can do for your teeth, besides regular brushing. They used to use baking soda and salt in the olden days instead of toothpaste and use that for cleaning. But it is a very slow process. Faster to get some teeth paint and paint them white.
