Why are some shark teeth white and some black?

Why are fossil shark teeth different colors? The color of fossil shark teeth is a result of the minerals that are present in the surrounding sediments. Teeth fossilize through a process called permineralization. As water seeps through sediments over the teeth, it transports the minerals that are found in the sediment.
