Fossilized shark teeth aren’t always black. They can be gray, brown, beige, or even red, orange, blue, green, or yellow. Bleaching and leaching after fossilization can also return the tooth to a white color. The color of a shark tooth or other fossil reflects the chemical composition of the sediment that formed it.
Do all shark teeth turn black?
Most of the time, shark teeth that you find on the beach are black because they’re fossilized. In the process of fossilization, the minerals that are naturally in shark teeth are replaced by other minerals that were in the rock or soil where the tooth was buried.
Modern shark teeth, both the crown and the root, are typically white in color. Fossil teeth are permineralized and are usually darker colored. There are instances where fossil teeth exhibit a white crown however the root is usually a darker grey or beige color.

Why are megalodon teeth black?
