The Whale shark - the biggest of all shark species (they're the size of a schoolbus), have tiny, primordial teeth - most shark experts believe they are useless, and that whale sharks are plankton and krill eaters.
Great White shark teeth as are those from all sharks are white. Black shark teeth are fossilized ones. The most common color for fossilized shark teeth is a black root with a grayish crown.
I bought a black shark tooth on eBay for seventy five bucks. so any were round fifty
Shark teeth are made up of calcium phosphate, which is the mineral apatite. Although shark teeth are sturdier than the cartilage that makes up their skeleton, the teeth still disintegrate over time unless they are fossilized. This is why you rarely find white shark teeth on a beach. Shark teeth are preserved if the tooth is buried, which prevents decomposition by oxygen and bacteria. Shark teeth buried in sediments absorb surrounding minerals, turning them from a normal whitish tooth color to a deeper color, usually black, gray or tan. The fossilization process takes at least 10,000 years, although some fossil shark's teeth are millions of years old! Fossils are old, but you can't tell the approximate age of a shark tooth simply by its color because the color (black, gray, brown) depends completely on the chemical composition of the sediment that replaced the calcium during the fossilization process.
a shark has 3 rows of teeth and about 3,000 teeth in a life time.

The length of a shark's teeth depends on the type of shark. The largest living shark, a whale shark, has teeth that are relatively small, even tiny. The smallest living shark, the dogfish, also has tiny teeth, while the great white shark has teeth the size of about 36 mm, or 1.43 in. But the largest shark to have ever lived, the megalodon, could grow teeth longer than seven inches long.
After about a million years the toothe of a shark will become black but still maintain many characteristics of fresh shark teeth. That is the way shark teeth "Petrify" while in water. While they are buried in land they will take more time for the pressure of the sand or dirt to "petrify" a shark tooth. Sometimes about 1.6 million years or more.
