our teeth are naturally yellowish. our teeth has 3 layers. the bulkiest layer is the second layer(dentin-which is yellowish). This gives color to our teeth. the shade of the dentin reflects on the outer layer (enamel- which is transluscent). as many say, the yellower the teeth, the stronger they are - well, that's because they may have considerable amount of dentin, therefore, in case of tooth decay, bacteria won't easily penetrate the pulp(the life of the tooth).the food we eat might also cause some yellowish stains, but these stains can be removed when you have your teeth cleaned by the dental professional.
