Enamel is the outer layer that covers the lower layer of your teeth which is called dentin. The color of your teeth is formed by the reflection of light off the enamel.

This also partially depends upon the thickness of the enamel and how much the color of the dentin shows through it.

Every day a layer called pellicle is formed on your teeth which can get stained by different foods you eat. Additionally, enamel also has pores that can pick stains.
