While it is true that teeth can lose some of their pearly white shine due to stains from dark drinks like coffee, soda, and tea, this is easily removed with regular brushing or during your regular trip to the dentist if you have let it go a little far! The most common reason for yellow teeth is below the surface. Underneath the outside layer of enamel is a yellowy core called dentin. As your enamel wears from acidic foods, grinding teeth, scuffs and natural aging, this yellowy layer gets closer to the surface, making your teeth appear more and more yellow. Genetics also plays a strong role in the yellowness of your dentin, or thinness of your enamel.
